Backup Central

Will permissions etc. be preserved for restoring if I do something like

although I'm not root on the remote machine? If disaster happens, would I be
able to rsync everything back to my local machine into /BACKUP, and then
call
rdiff-backup -r /BACKUP /

(or something like that)?


Yeah I think that will work fine. rdiff-backup in the 0.13 series stores
its metadata (like permissions) in a seperate file. This means that your
plan should work fine. I don't recommend backing up / completely - you
can find lots about that in the archives.
Thanks for updating the wiki :)

Great. I am also thinking about mounting the local backup directory
"nosuid,noexec,nodev" (it is /home), this should not affect rdiff-backup's
operation, right?

So rdiff-backup is not suitable for "crash recovery" type backups? I am
already excluding a list of directories:

/BACKUP/**
/home/tmp/**
/cdrom/**
/dev/**
/floppy/**
/initrd/**
/lost+found/**
/mnt/**
/proc/**
/tmp/**
/var/tmp/**
/var/run/**
/var/state/logcheck/**

No problem :)


btw: I just found out about SHFS. (http://shfs.sf.net) It lets you mount
directories via SSH. It performs quite well (~1-2MB/s) so it might be
suitable for remote rdiff-backup where only SSH access is possible.
I'll try doing remote backups that way.
