I'm using rdiff-backup since a long time to pull backups over SSH to the backup-server. Recently rdiff-backup crashed with Errno 36. So I deleted the file which had the long name in the source. However, I can't get rdiff-backup to work again. I keep getting the following notice:

Previous backup seems to have failed, regressing destination now. Regressing to Tue Sep 11 02:07:50 2012 Exception '[Errno 36] File name too long: '....

The file name pointed out here is in the destination. I've checked the path, and there is no such file. So, the file is not in the source, nor in the destination, but I keep getting this error. I though it might be possible to get completely rid of the last failed backup info, to start from the last working one. That is actually what rdiff-backup is saying. But it keeps on falling over this file which does not exist anymore.

Any ideas?

Is there a database where it gets the info about this file from, and where I can remove it?

OK. If found the cause of the problem: eCryptFS. The backup destination was located in my encrypted home directory. And obviously long file names are a problem. After moving the destination to an unencrypted folder outside my home, it works. For reference: the system is running Lucid Lynx, server edition, all updates installed.

Note that lucid is now 2.5 years old. You should upgrade to 12.04 LTS. – psusi Nov 18 '12 at 3:04
@psusi Lucid is still supported (even on the desktop), through most of next month. So yes, Andre should upgrade, but there is no immediate rush to do so. – Eliah Kagan Mar 4 '13 at 0:00
