Hi,
I've been looking at using rdiff-backup to keep backups of
some non-critical servers, and come across an odd problem. Trawling the
mailing lists/google seems to have come up blank.
I'm backing up from a Linux machine (2.6.1 kernel, ext3fs) to a Solaris
9 host (ufs).
Both hosts are using rdiff-backup 0.12.6.
Commandline used is:
rdiff-backup --exclude /u1/backups --exclude /u1/music --exclude /mnt
--exclude /dev --exclude /proc / backup::/u1/backup/kitten/
"backup" is an SSH host alias, and is configured to log in using ssh
keys.
The initial backup runs ok, and looks fine. Later backups run and sync
up large files ok, but any small (mostly < 1kb) files (noticeably
dotfiles and configuration files) seem to fail on subsequent backups
with a mix of error 100 and 103.
An example of the error messages generated:
librsync: ERROR: (rs_file_copy_cb) seek failed: Invalid argument
librsync: ERROR: (rs_job_complete) patch job failed: IO error
UpdateError u1/home/bcc/.irssi/config librsync error 100 while in patch
cycle

I'm rapidly running out of ideas short of trying a different backup
plan...
Any thoughts?

Maybe librsync on Solaris has a problem accessing large files? I seem
to remember it is easy to get Solaris into that state. Have a look on
the librsync SF bugtracker for ideas.

If I had to take a guess, I'd say that the blocksize or minimum file
size on the two filesystems might be different, and the code doesn't
know how to deal. |
