Is it possible to do a full file system level backup of the data directory, say once a week, and differentials or incrementals daily? I'm wondering if there are files that would normally be removed that a restore: Full then diff/inc would not remove and perhaps corrupt/confuse things. Process: Saturday: Full backup (reset archive bits) of data dir with database shutdown Sunday: Differential (don't reset archive bits) of data dir with database shutdown Monday: Differential (don't reset archive bits) of data dir with database shutdown Wednesday: Restore to test server using Saturday's Full and Monday's Differential. Obviously this works for regular files/file systems; however, I'm not sure this is a good method with postgresql as the resulting data dir *may* (?) contain extra files (or other issues)?
