It's just something that isn't fully implemented yet. Most of the pieces are in place. However, it will take more work to support only incrementals since that would require the original full and all incrementals to be kept forever, and an increasing number of incrementals would have to be merged together. That's why doing a periodic full is necessary. The solution would be to fill in each incremental as the oldest backup is removed. That said, doing periodic fulls is good practice since that's the only time the file contents are really checked. > Also, there is no '--delete' option used: an incremental is > now unaware of deleted files.

(besides the notion of removed files) The quirks are for tar and smb, not rsync. Removed and renamed files work with rsync incrementals. The significant missing pieces with rsync are hardlinks and ACLs. Hardlinks will be supported in the next release. ACLs will be supported with BackupPCd.
