Backups are not deleting, accumulating large number of .TMP files in backup location.

Thread needs solution

I am experiencing a problem where I am unable to manually delete backups from the Acronis Backup Advanced console.  We run a weekly full backup and a daily incremental.  When I select a set of backups to delete, the current activities view shows the deletion running, but it usually stops at a certain percentage and stays there for a long time.  Eventually it will complete, and not report any errors.  After that I go an look in the console and the backups are still there, and no disk space has been cleared.

I am also noticing a lot of .TMP files building up in the backup location.  I am wondering if this has something to do with the problem.   I did have a backup fail last week.  These .TMP files are taking up a lot of space.  It makes me wonder if some process did not complete, and is now causing problems.  I will post screen shots.   Thank you for any help!

I will also attach the log file.

Hello David,

Thank you for your posting! Do you have consolidation enabled in the cleanup settings? See Deleting or moving backups with dependencies. When this setting is active, the software will create temporary files of the same size as backup to be able to delete selected slices from the backup chain. This method allows to remove dependent backups without removing the whole chain, but is rather resource-consuming. Message: The disk is full tells that it could probably be the case.

Thank you, 

Hello Ekaterina,

Thank you for your responce.  I have the "Retain the backup until all dependent backs become subject to deleteion" setting selected.  I was able to delete the old backups I was trying to delete.  I had to change the retention rules and run them, and it worked.  I think it was due to Acronis deleting a backup in the chain when applying retention rules, but for some reason it deleted newer backups in the chain before deleteing the older backups as well.  I'm not sure what went wrong there, but that is how the disk became full.  I still have the .TMP files on the backup location, and I am wondering what to do with them.   Can they be deleted?  Or will they eventually be taken care of due to retention rules.  Also that link you sent me does not work, fyi.

Thank you for your responce.

Yes, you can safely delete/move to another location all .tmp-files. Only files with GUID-like names should stay in the .meta-folder, this is the metadata of archives.
Thank you, corrected the link.
