Hi.

Is it possible on Solaris 10 5/09, to rollback to a ZFS snapshot,
WITHOUT destroying later created clones or snapshots?

Example:

--($ ~)-- sudo zfs snapshot rpool/r...@01

--($ ~)-- sudo zfs snapshot rpool/r...@02

--($ ~)-- sudo zfs clone rpool/r...@02 rpool/ROOT-02

--($ ~)-- LC_ALL=C sudo zfs rollback rpool/r...@01
cannot rollback to 'rpool/r...@01': more recent snapshots exist
use '-r' to force deletion of the following snapshots:
rpool/r...@02

So it isn't as simple as that. But what needs to be done, to preserve
rpool/ROOT-02?

Actually, I'm not concerned (that much) with preserving the clone
rpool/ROOT-02. But I'd like to keep the contents of rpool/ROOT as
it was when I created the @02 snapshot.

Is the only possible way to create a backup of rpool/r...@02 (eg.
of the snapshot directory /rpool/ROOT/.zfs/snapshots/02) and then
restore it later on (eg. backup to tape, backup to someother filesystem
using zfs send|recv, rsync, tar, ...)?

Thanks a lot,

Alexander
