[rdiff-backup-users] Case insensitive filesystems -> assert not incrp.lstat()

[Alain Russell]

Hi,

Having a problem with a directory that has been renamed on backup source from capital to lowercase .. If I do --check-destination-dir everything seems ok and I can re-run the backup manually, but it will fail again. Backups have been going fine until this happened, they are triggered from the backup server and pull data from live server.  If I try and backup just this directory it appears to backup ok to a new test location so guessing its something to do with the local index file, but have no idea about Python ..

Both servers are running Mac OS X - rdiff-backup 1.2.8. The full dump of what's occurring below. Can this be fixed without starting again ? and how do I stop this happening in future ?

Thanks

Alain
