Dear Amanda Administrators.
What dump configuration would you suggest for backing up a ZFS pool of
about 300GB? Within the pool there several smaller 'filesystems'.
Would you :
1. Use a script to implement ZFS snapshots and send these to the server
as the DLE?
2. Use tar to backup the filesystems? We do not make much use of ACLs
so tar's lack of ACL support shouldn't be an issue?
3. Something else?
Question : If a use 2 can still use 'amrecover' which AFAIK would be the
case if I went with 1??
The host is a Sun Solaris 10 X86 box is that pertinent.
I'm not on Solaris 10 yet, and haven't used ZFS, but . . .
I understand that with ZFS you have zfsdump (just as with ufs I have
ufsdump). So you could usse zfsdump with snapshots. I'm guessing it
wouldn't be too hard to modify the wrapper I wrote for Solaris 9 that
uses ufsdump with snapshots and is documented here
http://wiki.zmanda.com/index.php/Backup_client#Chris_Hoogendyk.27s_Example
If you have that pool logically broken up into a number of smaller
pieces that can be snapshotted and dumped, it will make it smoother for
Amanda's planner to distribute the load over the dump cycle.
Shouldn't have any problems with amrecover.
