  1. You back up a machine to a tape,
  2. Backup fails with:

    Data are absent in cache


Issue in the product.


This issue has been fixed in Acronis Cyber Protect 15.

As a temporary workaround, you can use a backup scheme without incremental backups, e.g. the "Always full" scheme. See the documentation for details.
