Getting multiple backups every night

Thread needs solution

This PC runs a differential backup every night and, until a few days ago, one backup file was what I got. Suddenly it's started giving me six every night. Luckily my NAS has plenty of available space but it's still not behaviour I want to continue. I tried forcing a new full file but this didn't stop it. The file names are what you'd expect, given a job name of Daily: Daily_full_b2_s1_v1.tib then Daily_diff_b2_s2_v1.tib through to Daily_diff_b2_s6_v1.tib.

Reading though some old threads (look, someone does read old threads! ;-) ) on database recovery, I found a reference to schedmgr.exe which would zap all Acronis Scheduler. If no-one has any better ideas, I'll give that a try.

Please download the MVP Log Viewer tool (link in my signature below) and use this to review the log file for your backup operation. This should provide more information on why you are seeing multiple backups?

If able, please create an Acronis System Report zip file and upload to this topic using the File option below (if below 8MB in size) else will need a sharing link to the file.

The fact that all the duplicate files are being given consecutive chain sequence numbers suggests that you may have the same task running repeatedly rather than an error causing the task to be repeated.

If you want to try using the Acronis Scheduler Manager tool to check for duplicate scheduled tasks, then you first need to identify the cryptic id for the problem task.  Using the MVP Log tool is perhaps the easiest way to do this.

Above, shows my Win 10 SSD Diff E backup task with a cryptic ID starting A46C9D16-6E12..

Next, from the C:\ProgramData\Acronis\TrueImageHome\Scripts folder, confirmation of the associated script .tib.tis file for the backup task using the same cryptic id.

Finally, running the Schedmgr.exe tool (as Administrator) then issuing get list shows that task 1-21 has the same cryptic id as my backup task and looking through all the entries, the crypic id is only shown once, so there are no duplicate schedule entries.

If duplicate entries are found, then you can use the other scheduler manager commands to delete the duplicate ones.

Example: if you found duplicate tasks 1-5, 1-15 & 1-30 then you can delete the unwanted duplicates by:

task 1-15

task delete

task 1-30

task delete

The alternative method would be to just use task zap which deletes everything then go back into the main ATI GUI and reset the schedules for all your tasks one by one.

Steve, thank you for your usual extremely informative post. I have to admit I got bored waiting for my OP to be moderated so I just used schedmgr.exe. 'get list' only showed the two tasks I expected (daily and monthly) so I used 'task zap' to kill them off then reset the schedule within ATI. On the basis of last night's run, this seems to have worked.
