A local copy backup fails and an error similar to the following is presented:
ERROR : 19:28:28 Backup failed: newPosition > limit: (124776892 > 65536)
This happens when the local copy of the data gets corrupted, which could be for various reasons. One possible reason is connectivity issues if the local copy is kept on a network drive. We recommend using the local disk for local backups, since this location tends to be more reliable than a network location.
Run a backup with local copy disabled, then re-enable local copy before running another backup. If this fails, purge the local copy directory completely before doing a fresh backup with local copy enabled.
