Hello, In summary, i appear to have encountered a bug when attempting to restore files using rsync 3.0.0pre4 (matt) with stored ACLs (via --fake-super). The ACL information appears to be correctly stored as xattrs on the backup server; however, when i attempt to restore while preserving the ACL data, i get the following error:
ERROR: out of memory in get_xattr_data [sender] Questions: 1. Is this a bug in rsync? The filesystem? Malloc? 2. If this is not how i'm supposed to restore the files with their ACLs intact, how should i do it? A complete run down, including commands, output, and other supporting data, is located below. Finally, i apologise if this is not an appropriate place to discuss this particular release of rsync on (since it is, of course, Mr. McCutchen's release...). Thank you. ------------------------- Running rsync 3.0.0pre4 "matt" on both machines (BACKUP-SERVER and FILE-SERVER).
