I'd suggest taking a look at the mounted filesystems:
# mount | grep "/dev "
udev on /dev type tmpfs (rw,mode=0755)
In my case the /dev/ data is from a tmpfs, filled by udev; by that definition
it is created afresh on every boot.
But, depending on your boot process, you might need some files in /dev to be
used for init; they might or might not be done by your initrd.
For "normal" backups you can ignore the /dev/ directory; but if you have a big
failure, and need to recover your entire system, you might need some of these
nodes to be able to boot.
I know that this is not really helpful.
So my practical tip:
- either just take that into the backups (doesn't really change that often,
for me at least - YMMV),
- or, to be *really* clean:
- goto single user mode
- unmount your /dev
- copy the basic nodes that are persistent to some other directory,
- resume to runlevel 3 (or 5 or whatever you normally use),
- and commit them as /dev.
- Then define ./dev/** as ignore pattern, so no new entries will be taken.
On a restore you'll get the needed entries, and that should allow you to use
fsvs as full backup tool.
Satiesfied? Any more questions?
Regards,
Phil
