That is correct. Assign tape drives to the underlying host name and
create a stu that points to that host name.

Re: [Veritas-bu] Looking for suggestions vaulting/duplication-related

[Marianu, Jonathan]

Nathan, 
Are you using RMAN to back up the database.
There are many settings available to optimize RMAN-nbu disk to disk
backup.
 
Consider using a vault profile or running a script that:
-displays all images created on a client in the last n hours.
-that list is passed as an argument to bpduplicate and executed.
 
This allows concurrent duplication of the finished on-disk images, while
the backup is still running.
 
Run that script at a frequency/duration shorter than the average image
duplication time in order to keep the drive busy.
 
Two options for the Monthly copy are a parallel duplication to inline
copy or a serial duplication running one after the other.
 
The second copy could use a volume from a different pool.
That pool could be ejected from a different vault profile with its own
pic list.

Re: [Veritas-bu] VTL & NetBackup Best Practice

[Marianu, Jonathan]

 
Thanks Curtis,
 
I generally do not dup while I am backing up, other than images under
128k. (another important discussion)
The backups run at night to DSU, 1900-0600 and the duplication jobs run
during the day 0800-1600.
 
There are often a handful of network clients that are still running jobs
into the morning when the duplication starts.
The typical reasons are, the NIC has switched to half duplex, or storage
was added to the host that night.
If I was using VTL for network backups, these few clients would impact
duplication because their virtual tapes are still in use.
 
A smaller media size does mitigate this but does not eliminate the
problem and creates a higher media count. 
 
As to the other question, I use bpduplicate instead of direct export on
my VTLs.
Here are a few of my reasons:
-highest media compression
-higher degree of confidence in restoreability from physical tape
-prioritization of images that need to be duplicated first
-All versions of NBU, and brands of VTL and libraries support this
duplication configuration
-imageDB is aware of all image copies. I use that to report the RTE of
an application based on the different risk scenarios. (Restore from VTL
or restore from tape, the current location of that tape)

Re: [Veritas-bu] VTL & NetBackup Best Practice

[Marianu, Jonathan]

I use DSUs for network media servers and either DSUs or VTL for large
clients that need to be dedicated media servers.
 
Here are some things to consider with network based backups:
Using VTL: A slow network client will hold onto a VTL tape. The other
images on that tape are then not available for duplication which means
if there was a data center disaster those images would not have been
copied to tape yet. This impacts your RPO.
Using DSU: A slow client will only effect the duplication of its image
and not the image of other clients.
 
 
I use VTL on large clients to save money.
Under a DSU methodology I must allocate the san storage directly to the
host in a multiple of the size of prod disk space.
As the prod space grows the DSU space needs to grow. This must be
monitored, managed, and sustained.  There are hundreds of these types of
clients across many data centers.
In addition, that allocated DSU space is not available for any other
media server so there is a lot of unused, yet allocated storage, and
with no compression.  
 
With VTL I can put that head in front of the same storage and zone the
virtual drives to the media servers. The VTL arbitrates the access and
provides a shared storage resource accessible over a high speed SAN.
I have the ability to increase backup storage capacity without touching
a production client. 
In addition I get compression on that storage.

Re: [Veritas-bu] Media Server with multiple NICS

[Marianu, Jonathan]

Just to follow up.
 
The clients on a particular network segment --> should be in a separate
policy --> that policy would specify a network specific storage unit -->
that storage unit specifies either the IP or dns name assigned to the
Media server's IP --> that IP is in turn assigned to the media server's
NIC which is on the same network segment as those clients.
 
A single media server can have multiple names, (virtual media servers)
and multiple storage units assigned to each. 
As a suggestion, create one DSU file system. Underneath the mount point
create a directory for each storage unit.
Each storage unit will use its subdirectory for its images.
Assign the tape drives to the underlying host name, not the virtual
name.
Create a vault profile for each virtual media server that duplicates the
disk images to the host's tape STU
 
I have a couple hundred of these types of large client media servers
that are known by multiple names. Each media server writes to SAN
attached DSUs and duplicates to SAN attached LTOs in SL8500s, and it
works.

Re: [Veritas-bu] Media Server with multiple NICS

[Marianu, Jonathan]

Paul,

Each NIC on the media server should have a separate IP.
Assign each IP a name in dns
Ensure that the static routes are set up correctly between the media
server and the clients. This part is critical.
This means if you run a traceroute from teh media server to the client
it is sending the packet out the correct NIC on the media server to the
correct NIC on the client. 

Set up a unique storage unit for each IP assigned to a NIC servicing
clients on the media server.
As a suggestion, use the DNS name assigned to that IP.
You will need at least one policy per storage unit. 
Consider naming the policy based on the underlying the storage unit.
Group the appropriate clients in the appropriate policies.

Other pertinent settings are MPX, multipstreaming, and vault
duplication.

Here are questions for you; what type of storage units are you using?
Are you going directly to tape, VTL or to a DSU first? What kind of DSU?
Do you use SSO? Do you use vault?
Do the clients have multiple NICs as well?

Re: [Veritas-bu] master server with multiple interfaces

[Marianu, Jonathan]

What is the underlying reason for doing this?

Is the goal to improve the network throughput on the media server or do the 
clients have an actual need to be on four different vlans?

 

If you did it that way you would create a "virtual" media server entry for each 
ip.

The real challenge comes with the tape drives. Although the drives can be 
shared among the virtual media servers, with SSO, only one virtual media server 
can write to a specific tape drive at any one time.

Without going into too much detail you may have difficulty keeping all four 
tape drives running at full speed on one host. If they are not running at full 
speed the backup throughput performance will drop sharply.  

 

There may be better options if the goal is to just improve throughput.

-IPMP

-Ethernet Trunking.

Re: [Veritas-bu] Suspend or Freeze media

[Marianu, Jonathan]

Part 1 of 2

Matt,

This applies to 5.1 and below.

Also, triple check all advice because I could be wrong. I don't have access to 
production NBU systems so this is from memory and my notes. Also I am writing 
without providing a full explanation. So I will include some notes at the 
bottom for you to review.

And learn some basic awk. A few days of learning awk will save you weeks of 
typing. I train other NBU admins and that is one of the first things they learn.


--My comments--

Freezing and suspending are media attributes stored in the media database on 
the media server.
See field 15 of bpmedialist -l.

This is important because it means it does not impact the image db on the 
master.
The images will expire regardless of the media's attribute unless you change 
the image expiration (bpexpdate)

A frozen media is never put back into service unless you manually unfreeze it.
I think suspended moves back when the images expire, but I'm not 100% certain.

Another thing to remember is you can only freeze assigned media because only 
assigned media is stored in a media database. 

So to phase out LTO2:
 
-Make a copy of volDB on the master and the mediaDB on the media servers so 
that you can roll back.

-identify which LTO2 media is assigned (storing images) and which media is not 
assigned.
# vmquery -pn SCRATCH -l | awk '{print $1}'
This should list the unassigned media

-remove the Scratch LTO2 media from the library and sync the volDB.

-If you have expired tapes outside the library, use vmdelete to remove them 
from volDB.

-freeze the remaining LTO2 media using "bpmedia -m MEDIAID -h MEDIA_SERVER_NAME"

Re: [Veritas-bu] T2000 vaulting performance with VTL/LTO3

[Marianu, Jonathan]

My recollection is that during duplication from VTL to tape , it uses
the mpx originally set in the policy unless it is throttled down by the
vault policy but you can't increase it. The MPX is what is so
interesting to examine in truss because I observed that any multiplexing
will impact the duplication speed.

 

This is impact more pronounced though when you are mixing slow and fast
clients together because the fragments are not spread out evenly on the
virtual tape and bptm has to rewind the virtual tape and reread, causing
a delay to physical library which is torture on the physical tape drive

 

Then I observed that a higher MPX led to a slight improvement in
duplication speed. I would use 24-32

However there are other tradeoffs. In the end we decided to not use VTL
for network client backups for the new master server environment model. 

A problem with VTLis that a slow client backup will hold onto the
vritual media preventing me from using it for duplication. This impacts
the RPO of other clients backups. DSU does not have that issue.

We use 64TB EVA file systems per network media server which give pretty
even performance and we use vxfs.

One outstanding issue with file systems that you don't have with VTL is
fragmentation Another benefit of VTL is that I have a media server
dedicated to writing the backups and another media server dedicated to
duplicating backups.

Something you wrote didn't sound quite right.
Bpbkar writes to the child bptm using TCP sockets which is a bottleneck.

The child bptm process or processes, depending on MPX, write to shared
memory, The parent bptm reads from shared memory and writes it to the
tape.

I still use 5.1 so this may be different in 6.0

[Marianu, Jonathan]

The MPX setting of the original backup can greatly influence the speed
of your duplications.

I'm not *telling* you to use a high mpx but it is something to consider
testing.

 

It is very interesting to open up two ssh sessions, put them side by
side and run a truss on both the reading and writing bptm processes of
the media server while a duplication is running and then rotate your
screen 90 degrees to the right.



That illustrates the effect MPX has much better than I could describe in
words.

Brian,

This will not have an effect on what is configured as a db client.

That information is defined in the policy database, not the client
database.
Although the commands looked similar,
-bpplclients queries and updates the policy db
-bpclient queries and updates the client db.



Type bpclient without any options and that will provide information on
how to use the command.

To query using bpclient there are multiple options.
NBU provides a human readable form, in general for most commands, it is
a capital L.
For output that you can parse in a script use a lower case l

To see all clients it is something like "bpclient -All -L"

Yes, I know of the bpmount command. I mentioned it in my original post.

 

I have considered putting the bpmount command in a bpstart_notify script
and then using bpgp to receive a copy of the output.

The challenge to that is deploying this to the vast number of clients.

I could use bpgp to copy the script to the client but I would still have
to make it executable to run and I do not know how to do that through
nbu.

 

 

Currently, I am analyzing the packet sent by the master to the client
when issuing the bpcoverage command.

It instructs bpcd to run a remote bpmount -i and bpcd passes back the
information so it looks like bpmount is the key.

 

Does anyone know how to programmatically pass commands directly to bpcd
daemon?

I have tried cleartext commands in telnet but the connection closes.

Bpmount does provide this information but I have not yet determined how
to run this remotely against another host.

[Veritas-bu] Identify drives in use

[Marianu, Jonathan]

Here is a possible answer to your problem. 
I have a script that combines these commands into a more condense
version but here I broke it into several logical commands to make it
easier to understand.


This command provides a list of the TLD robots defined on the control
host
tpconfig -d | sed s/,// | awk '/robotic path/{print $5}'

Once you have the path to the L700 run this command
echo "s d" | tldtest -r /dev/PATH_TO_L700 > /tmp/foo

Redirect that output to a file and filter out the non relevant
information then redirect that to a file.
cat /tmp/foo | egrep "^drive|^Source address|^Barcode" | sed s/\)//g >
/tmp/foo2

Run the following awk command against the output and it will list all
drives in use, the MEDIAID and the original SLOT# so that ops will know
not to put a tape in that slot.
awk '/yes/{DRIVE=$2; getline; SLOT=$6; getline; MEDIAID=$3; print DRIVE,
MEDIAID, SLOT}' /tmp/foo2


Please let me know if this was helpful.

Re: [Veritas-bu] Identify drives in use

[Marianu, Jonathan]

 

Two ways to obtain a list of all tape drives logically in use by media
servers across a netbackup environment:
1 vmdareq (not always accurate)
2. bpstulist (to obtain a list of media servers)
   vmoprcmd -h $MEDIA_SERVER_NAME -xdraw 
   The output provides a list of all drives in use.

To obtain a list of what drives are physically loaded use a tool that
queries the library directly.
If the robot is a TLD use tldtest as shown below:
echo "s d" | tldtest -r $ROBOT_DEVICE_NAME You can obtain the robotic

[Veritas-bu] Block or file level

[Marianu, Jonathan]

 
Shashi,

The netbackup process on the client, bpbkar reads the files from the
file system and creates a tar file that it streams over the network to
the bptm process running on a media server. The file is written in a
standard gnu tar format to tape. If needed, you can read the information
from tape without netbackup just using gnu tar. 
A caveat is that if you enable multiplexing the bptm process combines
and intersperses fragments of multiple tar streams to tape and then it
would be more difficult to read from tape just using tar.

Hi All

I have a small traditional LAN based backup setup with NetBackup 5.1 . I
created a policy on my backup server to backup a specific directory from
a backup client, and the directory sits in a traditional UNIX file
system on my backup client. My question is, when the policy triggered,
is the data traveled from backup client to backup server is in terms of
block level or file level? . I am getting different answers from
different people, please anyone clarify my doubt. Thank you.


Thanks & Regards,
Shashi Kanth

[Veritas-bu] Changing expiration date

[Marianu, Jonathan]

 
Yes, if you expire a piece of media then the image copy/fragments on
that media will also expire.
If you don't expire but just change the expiration date on the media
then I *think* the images will all pick up the new date as well.
Try it out and check it with bpimagelist.

[Veritas-bu] exchange backup without truncating logs

[Marianu, Jonathan]

There are a few things that could cause the status 69.
When it happened to me it was the client name. I was use the name
assigned to the backup interface on the host instead of the name
assigned within exchange.
The rule here is that the name of the client must exactly match the name
embedded in the exchange configuration.
It must match exactly.
Here is the configuration for one of my exchange policies. You can
compare your policy and look for any differences.
Consider using my include list to see if it works.

Good Luck.

[Veritas-bu] bpsetconfig Query

[Marianu, Jonathan]

 
Dave,

You can create a file that contains the parameters you wish to set and
execute
bpsetconfig -h $server FILE_NAME

to obtain the list for clients use bpplclients.
At this point you have two options; a for loop or an awk script.
for i in `cat bpplclients.ou`
do
bpsetconfig -h $i FILE_NAME
done

Alternatively you can use awk:
bpplclients '/PC/{print "bpsetconfig -h " $3  "FILE_NAME"}'

Hope that points you in the right direction.
There is a lot more to know about bpgetconfig/bpsetconfig

Agree with comments here with Paul. As I mentioned, most of this relies
on the type of Data you as a business are backing up.

And its not likely the business is going to want to change the way they
create their Data.

If you get 400GB on a tape, you should be happy; I have seen around
600MB crammed on a tape, but like a pint of beer, if you leave the tap
running, you need another glass to fill it.

And I will gladly drink it :-)

Not to be pedantic, but you're getting as much data on the tape as the
tape can hold. :o\

It's a 400GB tape, so it will hold 400GB of data, which may translate as
800GB of highly compressable data..how compressed your data starts
out is dependant on the type of data..

ie, lots of plain ASCII text files and you might be able to compress
800GB onto the 400GB tape, but images, music, dense DBs, etc, you might
only get 450GB on a tape.either way, "getting your money's worth" is
kind of an odd perspective.
If you're paying more for larger capacity tapes, you're paying for the
native capacity. The compressability of your data isn't determining
value.
If you're looking at value in a Gigs/Dollar perspective, you may or may
not want the larger tapes, you may want LTO1 or 2. I haven't looked at
costs lately.
The value in larger capacity tapes is in the overheadless media to
manage, smaller library footprint, etc, etc.
The TCO is lower, even if the Gigs/Dollar ratio isn't the highest.

Your data is your dataYou typically can't change that.
I'd imagine your company isn't going to change their Line of Business so
they have more compressable data to backup. :o)

Sorry if this provided no help at all, as far as answering your
question, but I suppose it's food for thought.

Paul

How do you determine the efficiency of your tape usage?  i.e. I was just
asked recently about our use of LTO3 tapes since they can hold up to 800
GB compressed, how much we were actually consuming.  i.e. if we are
getting our money's worth for the larger capacity more expensive tapes.

Thanks

[Veritas-bu] Tape went down due to room temperature

[Marianu, Jonathan]

 

1. Tape went down due to room temperature (Asif Iqbal)

Asif, 
You can remotely up a drive but you first want to ensure that there is
no tape in the drive or else it will go down again, and cause a backup
falure.
>From the host connected to the library robot use robtest, pick the
library and type "s d" and then press return looking for Drive 3. 
Then press q twice to exit. You don't want to stay in robtest too long
because it prevents nbu from sending any mount requests.
If there is a tape in there you must eject it and move it back to a slot
in the library, and run vmupdate to update VolDB.

There are two ways to eject a tape and up a drive. One way is remote.
The other requires you to log into the host.
Remote method
vmoprcmd -h $MEDIA_SERVER -reset 2  (This attempts to eject the tape and
move it back to the slot)
vmoprcmd -h $MEDIA_SERVER -up 2  (This ups the drive)

If you log into the media server use the command
mt -f /dev/rmt/1cbn offline (This ejects the tape but leaves it in the
moun=th of the drive)
Then log back into the host connected to the robot and use robtest to
move the tape back to a slot, robtest, "m d3 s#)
Then from the media server type, tpconfig -up 2.

Let me know if you have any more questions.

I have a tape went down due to overheat room temperature. The room cool
down since then but the tape still shows down. Is there a way I can
bring it back up remotely?

Hi,

 

I am planning NetBackup installation.  I need to know what licenses I
need for Exchange Server.  

 

I have one Master server and one set of Exchange clustered server
connected to SAN that I would like to backup.  It will be a SAN backup.

 

Please let me know what licenses I should order.

 

Thanks

 

Kathy

[Veritas-bu] LTO3 throughput on Vault/Duplication jobs

[Marianu, Jonathan]

The use of any multiplexing has an adverse effect on duplication
throughput.

To maximize duplication performance either turn MPX Off or set it to a
high number (as much as 32).

Setting MPX to 1 (off) provides the best duplication performance and
restore performance but if there are not enough front end client facing
drives on the media server the backup streams will queue up behind slow
clients. 

If you can not turn MPX off, setting MPX to a high number provides
better throughput during duplication than a lower number because there
are more bptm processes reading from the tape. If it is set lower, like
8, only 8 processes can read from the tape; then the tape has to rewind
and then 8 more processes read, then it rewinds and it keeps doing this
until all images are finally duplicated. The tradeoff is that a higher
MPX setting means that a restore will take longer.

It is important to note that MPX is set during the creation of copy 1 of
the image.


Here is a method for visualizing vault duplication from VTL to tape on
Solaris.
I find this helps our new netbackup admins to understand duplication
better.

Start duplication
Identify the two PARENT bptm processes involved in the duplication.
In two separate windows run "truss -p" against each process id.
Place the window monitoring the reading bptm process on top of the
writing window.
Now you can see a visual representation of the images being read fromm
tape and written to tape.
