Hi Jakob. That depends on the application using those files. If we are taking about a source code repository like subversion, having some files new, some files old like that might make the repo unusable anyway.

You can still restore from machine 2. The history will probably be broken and the latest backup will at the filesystem level not be a perfect snapshot in time (if you aren't using LVM snapshots you don't get that snapshot in time anyway). But every file in the latest backup on it's own will be consistent (rsync does not modify files in-place). So, you will have some files that are from the latest backup, some that are from the one before. Acceptable IMO.
