Re: Datadomain / Exagrid - Backup Times over Cat5

[Andrew S. Baker]

If all of your backups are from Box A to Box B, then both will need to be
trunked for there to be any benefits in throughput.

However, if there are multiple concurrent backups at play from multiple
sources, then trunking on the backup device will still provide for more
throughput than a single network connection.

Of course, as Kevin points out, there are several other factors to consider
in a backup scenario.

Re: Datadomain / Exagrid - Backup Times over Cat5

[johonn2 _]

We don't use DD or Exagrid but i can give you some numbers on that size.

We do a NAS backup not through NDMP.  4.3TB ~5.6 mil files.
NAS and backup media server are LACP'ed at 4Gig.  We hit at least 2.4Gbps
on the media server nightly
We dedup at the mediaserver for the NAS

A new full takes ~2-3 days using one stream.  Multi-streams i could get it
under 1 day.
Incr takes 9 hours single stream, pretty regular at 140GBs and 1.4 mil files
We no longer do real fulls and instead do synthetic with take 16 hours to
compile.

Our Friday INCR which includes PST files takes 19 hours, ~1.4 mil files but
the sized is increase to ~640GBs

We have another file server with 12TB and some where close to 20 mil files
We multi stream this server  with Dedup at the client

Incr backups of 1.6 mil files at ~36Gbs takes about 4 hours.
A raw full takes almost a week.


While backup technology is changing for the most part when an incremental
is completed you are still scanning every file to check the modify date or
archive bit.

I am not sure about DD or Exagrid but for us Netbackup they started
tracking file changes to dramatically decrease the full backups.  Not that
we have the latest version to take advantage of this.


If network bandwidth is really a challenge and not file count then look to
spreading out your fulls less often.  Do a Full backup every 1-2 months, a
differential every week and an incremental every day.  We do this for our
DNA sequencers which spit our 2TBs a patient.  We do a twice a year,
differential every month and incremental every day.

  This is where the "other things" come into play.  If the
change-delta, de-dupe, compression, and other magic happens on the
agent side of the backup, you may see significant gains.

  For example, if you're backing up a bunch of small files, and churn
is low, and the backup solution uses the "maintain a full mirror of
original" model, and it only copies the changed files, your nightly
backup might only need to ship a tiny amount of data over the wire.
Or if they're large files but it has good change-delta handling.

  Even without such magic, you may also be able to do a longer full
backup on weekends, then an incremental/differential on weeknights.

RE: Datadomain / Exagrid - Backup Times over Cat5

[Bourque Daniel]

Not necessarily, don't mix capacity with speed.  A 2 link Port-Channel is still 
2 x 1 Gbs link.  If the backup is between only 2 IP (not multiplexing backup 
from multiple sources), the Port-Channel algorithm will still give you only 1 
Gbs per IP pairs or port pair, etc.  You have to check the load-balancing 
option of the Port-Channel in your system.  There is multiple algorithm 
available to load-balance in the Port-Channel.  You have to chose the correct 
one for your system.

  That depends how fast the network you're running is, and how 
much
data you've got to worry about, and maybe other things.

  Gigabit Ethernet can stream 125,000,000 8-bit quantities per 
second.
 Framing and protocol overhead rob significantly from that.  
Let's
assume 75% efficiency, just to have a number.  That's 93 
megabytes per
second, or 337 gigabytes in one hour.  If you're only backing 
up a
terabyte, that might be just fine.  If you're backing up a 
petabyte,
not so much.

Re: Datadomain / Exagrid - Backup Times over Cat5

[Jon D]

Thanks everyone. It seems like it's as simple as the Cat5 cable is the
bottle neck.
I think DD does have a pre-backup dedupe, but only if it's talking to a
server with a client loaded.
Wouldn't help with backing up file shares on an EMC SAN.

Somehow I need to figure out how to get data on 1 EMC SAN(acting like a
NAS) to get to a backup appliance with speed.
Without dropping 10G money. lol

Re: Datadomain / Exagrid - Backup Times over Cat5

[Richard Stovall]

Can't speak to Exagrid, but think of the DD boxes as if they are NAS
devices.  My (older model) 530 can ingest data as fast as I can throw
information at it.

Regarding speed, I suppose too slow is as too slow does.  GigE is fast
enough for my backups given their size.  Here are some statistics about
amount of data written over the last week and compression ratios.

Pre-Comp (GB)   Post-Comp(GB)   Global-Comp Factor   Local-Comp Factor
 Total-Comp Factor (Reduction %)

RE: ExaGrid

[John Hornbuckle]

We're still ironing out a couple of weird things, but overall I've been 
pleased. I'm SO glad to be rid of tapes, and backups are much quicker. 
Restoring files is a breeze, too.

With our backup patterns, the de-duplication process is very effective. We're 
currently getting a > 28:1 ratio.

Note that Exchange GRT backups don't currently work correctly; the company says 
that will be fixed within the next couple of weeks. GRT Hyper-V backups don't 
work, either, but the fix for that is longer on the horizon (not surprising, 
since the Backup Exec Hyper-V agent is brand new).

I should have added that we lost 500 GB of storage due to heat issues last

The EDU discount may change that for me.  It is the only reason I enjoy
working in this environment, otherwise it really is not fun.  I am hoping
that it is good and will save me having to pay for a replacement for our
existing software package.

RE: ExaGrid

[Tim Vander Kooi]

I looked at ExaGrid about a year and a half ago. I couldn't come up with valid 
justification for spending that kind of money on a disk backup system, when I 
could purchase disk from EqualLogic or NetApp for less cost and use it for many 
different purposes.

How are you liking the ExaGrid system?  We have not got the money in place but 
I still need to look at this as we are going to have to change our existing 
backup solution, it does not do VM's nor does it do 2008.  Since we dropped 
support last year we are looking at this one to even get rid of tapes as well.

Does anyone have any experience with ExaGrid's disk-based backups? I'm
about fed up with tape drives, and we're in the market for some new
servers. I'm contemplating ordering them without tape drives and using
something like what ExaGrid is offering instead.

Does anyone have any experience with ExaGrid's disk-based backups? I'm
about fed up with tape drives, and we're in the market for some new
servers. I'm contemplating ordering them without tape drives and using
something like what ExaGrid is offering instead.
