Also, dump/restore allows you to use snapshots on a live filesystem (I
would test it properly on a large FS with heavy activity).
But it's worth pointing out that this is fully possibly with any backup
tool - just run mksnap_ffs and backup a mounted snapshot. I do this with
rdiff-backup for example.
Now, if you are worried about "backing up the whole filesystem"...well,
just tell dump not to dump it :)
man chflags (in particular, the nodump flag)
man dump (in particular, -h )
The problem with this is for me two-fold:
(1) It's a global property. I can't take different backups that
include/exclude different things.
(2) I can't easily express "backup /usr/var/db/my-important-database"
without seting "nodump" on a bunch of stuff except that. In other words,
I want exclude by default, while dump and the chflags system provides
include by default.
That said I do like dump's integration with snapshots and overall
coherent feeling. If backup diskspace and bandwidth was not a concern
I'd use it.
I want to thank everyone who contributed to this thread. You've given me a
great deal to think about. I'll be reading over the responses again,
carefully, and decide what I think the best answer is.
