Backup Redirected To C: Drive, Fills Drive And Fails

This may be due to a defective release of the Acronis software.  A similar problem followed a buggy release a year or two ago.

Backup failed last night due to lack of storage space.  Looking at my NAS, there appeared to be sufficient space but there was an unusually large backup for one week in May.  I deleted the May backups, keeping the June backups.  

I manually retried the backup, but it failed again due to lack of space.

I then discovered that my C: drive was full because the Acronis backup had been routed to the C: drive (root) and not the NAS.  As noted, this same thing happened a year or two ago when Acronis released a buggy version.

Acronis still shows the NAS as the target, but with a broken connection.  When I try to re-link to the NAS, Acronis says that the existing backups on the NAS won't be shown unless I add them.  [Previously created backup versions will not be shown in the Recovery tab of this backup. To recover them, first add them as an existing backup.]

I created a new backup going to the NAS, added the existing/surviving backups and ran the backup.  The backup still went to the C: drive.

The only other variable is that I upgraded to Windows 11 a week or two ago, but the Acronis backups were working fine until last night.

Is anybody else having a similar problem?  If so, have you been able to reach Acronis?  (I sat in phone queue and then got dumped to voice mail.  No return call yet.)  Is there a known (permanent) solution?

I found the original thread from when this happened in 2019...............and again in 2021.

 

https://forum.acronis.com/forum/acronis-true-image-2020-forum/true-imag…

 

The workaround appears to be the same............disable the MMS process.

 

After all the grief this caused in 2019, and 2021, I would have thought that Acronis would have included this issue in their regression testing of new releases and/or datacenter maintenance.

This just happened to me within the last couple of weeks.   I tried all the steps mentioned above and it continues to backup to c even though the new backup routine indicates my NAS's backup directory.

Running the latest updated build of True Image 2021 on my Windows 10 PC.  

Several weeks ago I started running into this exact same problem.  Instead of backups going to my NAS they were going to C: drive root directory and then failing when C: drive ran out of room. I tried lots of solutions like deleting the backup routines and rebuilding them.   

I also found that if I started the backup immediately after building it that it worked properly backing up the the NAS, but then the next automatic nightly backup once again tried to backup to C.

I tried to look at the thread about the MMS but got a little confused, particularly due to the length of the thread and the level of the technical answers.  None the less I tried running the services app on my windows 10 PC and disabled the "startup type" of the "Acronis Managed Machine Service Mini as shown below:

But the same thing happened last night (backup went to C drive and not to NAS).    

Is what I tried the correct way to disable the MMS?  Is there something to the solution I'm missing or is it just not working for me.  And does anyone have any other suggestions?

This is an Acronis issue - see forum topic: True Image 2020 -Backup option settings loss

I can only recommend that you and any other affected users contact Arpita Ghosh who is the new Acronis Product Manager for these home products! (Arpita.Ghosh@acronis.com).

Note: it should only be necessary to set the AMMSM service to Manual rather than Disabled but it is also recommended to sign out of your Acronis Account if you have a Perpetual license product.

Since this same issue happened in 2019 and 2021 I'm giving up on Acronis and migrating to Macrium.  Other users are reporting performance improvement on their systems after uninstalling Acronis.

I have also seen reports for ATI 2016 with the same issue of NAS backups being redirected to the C: drive, as well as for ACPHO too!
