We currently have 2 hosts performing backups. One of the hosts are off-site , and perform incremental backups. A lot of the time, we are greeted with the following error. These backups sometimes run for 4-10 hours, then fail. Other times, these backups run just fine without a problem. What could possibly be causing this from happening? The backups on the main host that perform full-backups are running fine. The incremental backups are causing these errors.
