Can I backup fs containing holding disk?

2002-04-27 Thread James Long

I'm brand new, so let me first say thank you, this looks like a pretty
full-blown backup implementation.

Bunch of new user questions: can I put the holding disk on one
of the file systems I'm backing up (backing up the tape server host
itself)?

Does amanda backup the entire filesystem, both the used space and
the empty space?  Since it uses the fs /dev/ entries, do I need to
be concerned about symlinks that cross slices?

I'm using a Seagate Scorpion DDS-2 (4G/8G) drive.  Should I skip amanda's
compression and use the hardware compression?  I've been using tar, and
I made uncompressed tar files of about 1.8G and 1.2G and used hardware
compression to get them to both fit on a 2G/4G tape.   But I've added
more content, and now the 1.8G file is over 2G, and tar seems to use a
signed 32-bit int, so I'm hosed beyond 2G (.tar cannot contain any single
file over 2G).  So since the tape is a .tar file itself, it was crapping
out on the 2G file.

Here's what I used to do:

/usr/bin/tar -cf /var/spool/backup/ns.tar --exclude /mnt --exclude /dev --exclude 
/var/tmp --exclude /var/spool/backup --exclude /var/squid --exclude /usr/tmp --exclude 
/usr/home/smbd/MP3 /

Then I'd tar _that_ file (ns.tar) and one other similar tar file from 
another host onto my tape drive.  _That's_ what wouldn't work once
ns.tar grew beyond 2G.

Sorry to ramble.  I think I can dig enough to figure out amanda's 
exclude mechanism.  Do I need to explicitly exclude the directory where
amanda is putting the dump images, or will amanda know to do that?
How does amanda handle symlinks that cross filesystems?  When an excluded 
directory is a symlink, should I exclude both the physical dir _and_ the 
logical link, or just the physical dir?

Here's what I want to back up.  Subtract about 2G from /usr/home
for stuff that doesn't have to be backed up, and another 3-3.5G on
/usr that doesn't need to be backed up.  /var/spool/backup is a symlink
to /usr/tmp/backup, and I'm putting my holding files under 
/var/spool/backup.  Hence the question about excluding symlinks, will 
amanda know to exclude /usr/tmp/backup/dumps because that's where 
/var/spool/backup/dumps resides?


Filesystem  Size   Used  Avail Capacity  Mounted on
/dev/idad0s1a   124M83M31M73%/
/dev/idad0s1h   9.7G   5.0G   3.9G56%/usr
/dev/idad0s1d   4.9G   3.1G   1.4G68%/usr/home
/dev/idad0s1e   124M64M50M56%/var
/dev/idad0s1g   992M37K   913M 0%/var/spool
/dev/idad0s1f   124M73M41M64%/var/tmp


Holler if I can confuse this a little more.  The evening is still
young here on the left coast.

Thank you!

Using AManda

2002-04-27 Thread Vijay Kumar

hi!
I am a beginner here.
 ACtually i need to backup a NFS mounted file system 
(only /home) from a linux client/server on to iself or any other linux 
client's hard disk (sorry no tape drive business!).
How shd I configure my amanda-conf for this? 
And what would be reasonable values for dumpscyle , tapedev,tapechanger?

Also the previous mails told me that dump was not recommended for 
linux?and that one hsd go for tar ? Is that so? 
i have tar 1.13.17 . Will that be good or do i need to upgrade to 1.13.19 
.Also i dont have readline, termcap. Do i also need to install them?

Vijay

Re: Amanda + solaris

2002-04-27 Thread Wayne Richards

Good morning all,

The sgen driver works well on Solaris 8.  That fixed my need to roll my own. 

The only change I needed to recognize the HP C7200-8000 changer was to modify 
the sgen.conf with the following lines:


device-type-config-list="library";

inquiry-config-list="HP",   "C7200-8000";

and of course uncomment the:
name="sgen" class="scsi" target=0 lun=0;
 .
 .
 .
lines.

mtx works very well with the changer and the DLT8000 drives.

Thanks to Jon LaBadie, Thomas Hepper and Craig Dewick.
