Backup cleanup deleting wrong files

Thread needs solution

I have been using Acronis since 2009 and this is the first time I have noticed this problem.

I have two different backup schemes: one that runs MWF and backups to a NAS, the other runs TThS and backups up to a USB external drive.

Both schemes are set to create FULL backups, and keep 1 version, the intention being that I'll always have one backup from the MWF backup available and one from the TTHS also.

But now for some reason each backup as it completes deletes backups created by the OTHER backup, in the OTHER location. In other words, the MWF backup deletes the backup created by the TThS backup, so that the one just completed is the only one left. This is NOT acceptable and I'm positive this is not the way this has worked previously. Doesn't even make sense that it would work this way, since the two backups could be entirely different and unrelated.

Can someone tell me how to set this up so the two backup schemes don't interfere with each other? I've just recently upgraded to 2015 .

Thanks,
Judy

When upgrading to a complete new version, it is usually best to start over with completely new tasks.

So, my suggestion to you is to start over with new tasks.

While creating the task for the NAS, do not have the external connected.
When creating the task for the external, the external must be connected.

Set up each backup scheme as a "custom' scheme as per example GH11. If you have the storage space, consider keeping more than "store 1 recent version."

GH11. Create Custom Full Backup Scheme w/auto cleanup....Store/Keep 4 versions (chains). Use whatever number best fits the individual needs..

If you set up email notification, that can help to make sure you know the results of each backup.

Depending upon the type of backup scheme you wish to create, here is an example of each type. These can be set up for Disk image, or Partiton, or Files-folders backups. These example show how to set up automatic cleanup so the program will do the deletion after it reaches your set goal of how many chains to retain.

Editing an existing task is not recommended. Rarely does an edited task perform to user expectations. It is usually better to start with a new task using a new non-identical task name and point to a new storage sub-folder so each task has it own storage folder/sub-folder. Old task can be stopped or deleted from the task listings.

GH11. Create Custom Full Backup Scheme w/auto cleanup....Store/Keep 4 versions (chains). Use whatever number best fits the individual needs..

GH12. Create Custom Incremental Backup Scheme w/auto cleanup. ...Keep Full plus 6 Inc per chain. Store/Keep 4 chains. Use whatever number best fits your needs.

GH13. Create Custom Differential Backup Scheme w/auto cleanup. ...Keep Full plus 2 Diff per chain. Store/Keep 2 chains. Use whatever number best fits your needs.

Thanks for your reply. I will review the info you have provided and recreate my backup tasks. To clarify something, this problem actually started just before upgrading to 2015 -- that was one of the reasons I upgraded. However, I HAD edited the existing backups to change one of the backups to a new location, and had also edited the other one because it had lost the credentials for the NAS. So those changes could have messed something up. (Although it certainly seems like you should be able to edit a task without causing that kind of problem.)

Thanks again. I'll report back if this doesn't correct the problem

Sadly, my experience has been that editing the cause just causes more problems than it corrects.

From your desription of your last edit, it sounds like the "move" option would have been the option to use, if you wanted to make a change to the task. Do report back some time later with your resuts--good or bad.
