Specify drive name instead of letter?

Thread needs solution

The target for my WIN10 laptop backup is a USB drive (f:\) and this is usually connected when I'm in the office. When a different USB drive is connected for non-backup purposes, and the drive is given the same letter, True Image starts a complete backup up to that drive. This is tedious at the best of times, and really awkward when the backup ends up on someone else's drive...

Is it possible to specify a unique drive identifier to True Image instead of a drive letter? If not, what is the best option to keep this from happening? Is it to just use a letter later in the alphabet for the backup drive and assume that it won't be assigned for anything else?

Oswald, welcome to these User Forums.

The recommended solution here would be to change the drive letter for your backup USB drive to be later in the alphabet via Windows Disk Management.

As an added protection against backups being created on the wrong USB drive, you could add a Pre Command to your backup task to help check for the correct drive before proceeding.

To do this do the following:

Create a small text file on the backup drive, i.e. BackupDrive.txt

Next, create a small batch command file with the following lines (change the drive letter to the one used by your USB drive for Acronis backups).  Save this as CheckDrive.bat on your computer.

echo off
copy S:\BackupDrive.txt S:\Temp

In your Acronis backup task, click on Options then the Advanced page tab.
Expand the Pre/Post commands section then click on Edit and select the CheckDrive.bat file.

Test that the command works when the correct drive is connected.

Rename the BackupDrive.txt file to xxBackupDrive.txt and test again that the command now fails.

When the backup is run to the correct drive, the Pre Command will be successful, but when a different drive is connected the task will fail.

Note: In the Advanced Options page, change the Error handling options to prevent the task from keep retrying and failing if the wrong drive is connected.
