Old backup are not deleted.
I have a problem on 2 PCs (Windows 10, ATI 2017 and ATI 2016).
The oldest versions of backups are not automatically deleted, and quotas are no longer respected.
On one of the PCs, the problem appeared after replacing the USB stick with a larger one.
I did assign the same letter, I even deleted the backup job and recreated it.
On one PC, after each backup Acronis indicates in the log sent by email: "Failed to open data stream. Try to remove the backup from the list, add it again by clicking 'Browse for backup' and recreate the backup settings."
On the other PC, Acronis sents an email when the external drive becomes full.
I enclose the scripts of the backup tasks.
Thanks for your help.
