Symptoms

You save backups to a NAS and the NAS has the recycle bin feature enabled.

After an archive is cleaned up according to retention rules, next backup fails.

Cause

The cleaned up slices go to the recycle bin instead of being permanently deleted, which causes backup failure on the next backup task run.

Solution

We recommend either disabling the recycle bin on NAS or mark the *.TIBx extension as an exclusion for the recycle bin.
