Backup Central

Hi all,

I'm trying to backup two filesystems over SSH from a laptop to my linux
server. The first has 4 gigs of data on an ext3 filesystem, the second
has 48 gigs of data on an ntfs filesystem, mounted under linux using
ntfs-3g.

The first filesystem is backed up successfully, but unfortunately I am
getting "[Errno 12] Cannot allocate memory" about halfway through the
backup of the second filesystem.

Both the server and the laptop are running rdiff-backup 1.2.8, the server
is using python 2.6.5, and the client is using python 2.6.4. The server
has 8 GB of RAM, and the laptop has 2 GB of RAM.

Here's the command line I'm using:
rdiff-backup --exclude-other-filesystems --exclude-sockets
/home/sarah/Data
backup < at > remote-backup::/nfs/media/backup/bode/rdiff-backup/home-sarah-Data

I've put a log of the backup here:
http://www.ccs.neu.edu/home/jfaulkne/bode-rdiff-backup.txt

and here's the same failure when using "--terminal-verbosity 7":
http://www.ccs.neu.edu/home/jfaulkne/bode-rdiff-backup2.txt

Anyone have any ideas as to what's going wrong here?

thanks for any help,
Jim Faulkner

Try copying the base data to dest with rsync first and then run rdiff-backup against it with --force.

That worked! The rdiff-backup finished successfully after an initial
rsync of the data. Why did I need to run rsync first to make it work?

Rsync is simply better (resume and other options) at connections across networks so this is a common method.
Don't forget to remove the --force option after the first rdiff-backup run and then run rdiff-backup again.
In my experience two rdiff-backup runs is required to be sure that the repo is working.

Also I usually recommend using backupninja instead off rdiff-backup directly to provide a backup system.
