direct links of old sources may well be a few messages off.


Just an update.  I'm not using gnutar instead of dump and it's working 
fine now.

Thanks

Kee

You can use GNUTAR instead of DUMP for the program field in your
amanda.conf.  That works for backing up my drbd partitions.  I
explicitly tell Amanda to back up the same mount point on both servers
where the drbd partition mounts.  It will only back up the primary
server's copy of the data but that's all I need.

For what it's worth Linus himself has come out against using
dump/restore.  He claims it's unreliable and the better option is to use
tar/cpio.  My first backups were done with dump/restore and can
understand why you would want to use it, but on Linux with Amanda gnutar
is the better answer.

Yes - It has the same permissions as /var (for example).  /var works fine.

Amanda uses "dump" to backup the partitions.

The man page for dump says

"...either a mountpoint of a filesystem or a list of files and
directories to be backed up as a subset of a filesystem.  In the former
case, either the path to a mounted filesystem or the device of an
unmounted filesystem can be used."

Because /home is mounted I have to use /home as the dump source.  I
could try and use /dev/sda8 but that sounds a little scary as it would
be bypassing the /dev/drbd0 device.
