I just tested a full zimbra backup on my mailbox with 308 client and 313 bricks and it completed in normal time with no errors. This is more evidence that the problem is client only and was introduced in 309-313.

This weekend with 313 the backup was only about 1/2 through after 5 hrs. I aborted the backup and the client crashed.
