Hi
We have a number of customers (~150) that have a single Sun server with
directly attached storage and directly attached tape drive/library. These
servers are currently running UFS, but we are looking at deploying ZFS in
future builds.
At present, we backup the server to the local tape drive using ufsdump, but
there appears to be no equivalent for ZFS. Is anyone aware why Sun have never
provided a zfsdump/zfsrestore for this sort of configuration?
Can anyone advise the best way to backup a ZFS-based server to a locally
attached tape drive? It is possible that the filesystems to backup are bigger
than a single tape, so multiple volume support is a must.
I thought about doing a "zfs send tank/f...@monday > /dev/rmt/0" but this won't
manage multiple tapes. Also, I'm not sure if this contains all the metadata
required to perform a bare metal restore.
Any help much appreciated!
Thanks
JR
