what is the zfs equivalent of ufsdump and ufsrestore? Are we to use zfs
send | tar and then zfs receive?
Is there ever to be a direct replacement of the features of ufsdump? In
particular, I like the way I can do incremental backups and interactive
I see with zfs that snapshots are possible, which might be good for
recovering from accidentally deleting files, but what about a regular dump
to tape for the purpose of disaster recovery in the event of total disk or
system failure? My main requirement here is that I can take the set of
tapes and rebuild the entire system on new hardware. Ideally I would like
to avoid changing tapes too often, so a daily incremental on top of a
weekly full dump seems appropriate.
And, in the event that the above is trivial, is it going to be easy to
interleave these dumps with ufsdump sessions on a single tape? (The system
in question has both ufs and zfs file systems, and both are in need of
The file systems in question are not very large (20 - 30 GB, perhaps to
grow to 50 - 60 GB). The target device is a DAT72 drive, locally attached.
The server itself is a T1000.
Any pointers would be greatly appareciated.
