Old backup are not deleted.

Stéphane, the task script files do not really offer much help for the situation described here, this is where the actual backup log files would be better suited to try to show what is happening?

First, please check the automatic cleanup settings for your backup tasks and check that they are still set correctly as you expect them to be and have not been disabled?

For the PC where you have changed the storage USB drive, please try creating a new task with a unique name that hasn't been used before and see if this will work correctly for you?

Note: as you are using older versions of ATI with 2016 & 2017, check what file system your new USB drive is using.  If it has exFAT then you would need to reformat it to use NTFS to work with your older ATI versions.

Hi Steve and thanks for your help :-)

I did what you suggested to me. I checked (on the only PC to which I have access this evening), the quota setting. This is in line with my expectations.

I also just noticed that on my own PC (with ATI 2019), I have 3 backups kept for a quota of 7 ! I think I deleted some extra backups over a month ago, and ATI has been a bit lost since ...

As for the USB keys, they are well formatted in NTFS.

Here is one of the error reports sent by ATI :

Stéphane, did you delete some backups outside of ATI by using Explorer?

If so, then this can cause issues because it leaves information behind in the internal database used by ATI to track the files it has created.

There are two options to try:

1. Validate the backup task and if any errors are shown via pop-ups, then take the Ignore option if offered, else the Cancel option - for each error.
    
2. Force the database to be rebuilt as per KB 60915: Acronis True Image: repairing program settings instructions.

Hi Steve.
