I'm beginning with FreeBSD, working on a hosted server. As it's not a very powerful one, I've left him under UFS (moreover, installation choices didn't give ZFS choice).
I want to save the whole system, for avoiding the painfully distant installation in case of a disk crash.
I've read that FreeBSD use dump/restore, on a frozen filesystem (frozen with snapshot system). I've read also that dump can be a pain with UFS journalisation (you have to
That's why I've decided to use the good old tar, which never deceived me before.
On Linux, I would do this:
- remount the whole root partition with

I guess I can do roughly the same thing with FreeBSD. Does snapshot replaces the
Are there directories I shouldn't backup? I'm thinking of skipping /proc, /sys. I'm wondering for /dev, I guess that it should be saved (on Linux, with udev you don't have to).
Please, tell me if it seems ok to you. Thank you.
