Thank you for your answer.
I have in fact experimented with this for a while already and created a shell script for automatic backuping of snapshots. I was however not able to restore the backups correctly - more specifically, I did not succeed in making the computer boot from the restored disc.
I did even create a topic about that on this forum
earlier. I described the steps I took to restore the snapshots and what the results were.
I have experimented yet a little more since then but still did not succeed and I have no idea what to try anymore.
Besides the steps that I described in the other topic I did also try to install the system to a new disc in a standard way and restore just the important filesystems (the system root and the user directories) but that did not work either.
That's why I thought the way I've chosen might be completely wrong and that I should create a more general question in order to find out the ways other people do that.
On my system hard disc I have the following filesystems:
- rpool
- rpool/ROOT
- rpool/ROOT/solaris (this is the system root directory)
- rpool/export (this is the root of user home directories)
