[lbackup-discussion] L-Backup Errors! That error occurs when rsync tries to set an ACE specifying a user that does not exist. Here's what happens: 1) Read ACE on source file --> on Mac OS X, the user or group of the ACE is stored using the user or group's UUID 2) Convert UUID to uid/gid using mbr_uuid_to_id, also store which type it is (e.g. user or group) 3) [transfer file] 4) Convert uid/gid to UUID using mbr_uid_to_uuid or mbr_gid_to_uuid 5) Set ACE on destination file

[Michael Williams]

The server is now Mac OS X 10.6.3.
rsync is either 3.0.6 or 3.0.7, I can't remember which.

The compilation was made following the instructions on : http://www.bombich.com/mactips/rsync.html
Where it is rsync 3.0.7 the version numbers were just substituted.

I am at a bit of a loss as to why this had suddenly happened as the servers backups were functioning fine.
I think I will deploy the alpha release and stop backing up the ACLs. The ACLs aren't important at any rate and if it will solve this problem then it will make my life considerable easier.

Thanks for your help.
Michael

This alpha release has been available for at least a few days and I am running this on a variety of systems without any issues. I fully understand if this is not a path you want to go down. However, with regards to an immediate solution this is the best advice I am able to offer.
