Acronis does not detect Hard drives automatically!

Thread needs solution

Hi Acronis Forum,

I have got a huge problem. Acronis does not recognize my USB hard disks automatically. We have two hard drives from the same manufacturer and the same model.
I switch the hard disk every day, that every second backup is safed to another hdd.
When the first backup is completed, the first disk is removed from the pc  and the second disk will be pluged in on the next day.

Here starts the problem. The second disk will not be detected by acronis. The hdd gets the same drive letter , as it is stated in Acronis. But Acronis does not recognize the disk and can not start the backup to it.
If we now plugin the first hard drive againit will also no longer be detected by acronis.
So the job must be re-created. After installing Acronis for the first time, it has worked for about a year. Since three weeks now it wont work.

Has anyone an idea how i can solve this problem?

Melissa, welcome to these user forums.

Acronis home products are not intended to be used in the way you describe where you are swapping the target disk drive used for your backup task to write to.  Acronis stores the unique drive identifier (UUID) of the target drive selected for the backup task when it was created in the database and then looks for the same UUID when the task is run again.

When you change the target drive you then introduce a different UUID for the new drive which will then not match the value stored in the database, even though you are using the same drive letter for the second drive.

The recommended method of working with multiple target backup drives is to pre-allocate different drive letters for each drive, selecting letters which are further down the alphabet, i.e. pick letters like S:, T: etc, so that these drive letters will not be allocated to any other USB devices that may be plugged in to the system.

Next, create a separate new backup task for each of your backup drives, using the drive letter in the task name to make it easier to identify which drive is to be used with the task.

ATIH 2017 is meant to have improved the handling for multiple target backup drives but I haven't test this myself personally to prove that it works without giving these type of problems.

Steve, I think it's the same in 2017 by design as well.  However, if your drive changes letters (the same drive), that is supposed to work now.  So, the hardware setup for the backup must remain the same, but if you set it up with D: and Windows assigns it E: because D: is already in use (say by a USB flash drive), then Acronis is supposed to be able to continue the existing backup to the E: drive since it has the same UUID (being it's the same physical disk that the backup was originally selected during the backup configuration).

  • The application now works correctly if a drive letter changes (available on Windows only).

 

What you have suggested was also my idea, if nothing else would help.
I will now set it up so that each hard drive will get its own job.

thank you for your help, steve.
