Very nice feature of solaris is to use a zfs snapshots to protect the current state\/configuration of a machine.<\/p>\n
And it is very easy to use, all we have to do is:<\/p>\n

After installation and configuration of various software we can create a new snapshot:<\/p>\n
beadm create -e solaris solaris-backup-2<\/pre>\nIf something bad will happen afterwards we can just simple select the backup at the boot manager! and then activate our backup as the active snapshot:<\/p>\n
beadm activate solaris-backup-2<\/pre>\nI think the old\/bad snapshot\/base can be deleted afterwards, but i didn’t yet tried that, maybe it is a good idea to create a base snapshot and working snapshot, and set the working snapshot as the active one, so in the case of an error we can create a new snapshot based on the base snapshot, and afterwards we can remove the bad working snapshot.<\/p>\n
