Attach USB drive error

I realize this is a known error.  I have troubleshot the error as per the help info without success.

I am backing up an external USB drive to an external USB drive.

The backup drive appears in Windows Explorer and I can copy files to it.  It is consistently drive K every time I plug it in.

Full-backups work, by the way, it's just the incremental ones that don't seem to.

Any help here?  Thanks.

Can you tell us exactly what error you are getting? If your external drive is powering down and turning off due to power profile settings for example, the application may not be able to locate the drive to perform the backup task.

The backup and source drives never power down.  I have attached screenshots of Explorer and Acronis.   

 

Interesting that full backups work but incremental ones do not.

Looking at your screenshots I am going to guess here and say that your problem is the way in which you store your backup files.  Every backup file you create shows to be in the same location (K:\ drive).  This I would say is confusing the True Image application as there are probably more than one file with the same name on drive K:\

You should have backups stored in individual folders for each backup task created.  In your case you have 6 individual tasks created in the same location.  By default each task has a name ending in b1_s1_v1.tib.  With several full files all ending the same True Image cannot determine which one the incrementals belong to.

Suggest you create a folder for each task file to be placed in on K: drive then edit each task to point to the new folder location and see if that corrects the issue.

That's a great guess, however....

Each backup is to different physical hard drive that is plugged into a hard drive dock when the backup is performed.  So yes they are all to drive K but there is a different full backup on each different physical hard drive used for backup

Does that make sense?

Thanks..

It does.  Are you certain that the incremental full backup on which the incremental scheme is based on on the physicla drive you think it is?

Even so, you still might have confused the True Image database used to track backup tasks with your arrangement.  Try the folder suggestion I gave and see what happens.

I would like to report success.

I went into the Options for each backup job > Advanced tab > Removable media settings:

I UNchecked "Ask for first media while creating backups on removable media"

The incremental backup worked perfectly..

Thanks for all your help.

Glad you got it sorted!

I'm having the same exact issue.

I have 2 backup tasks:

1 copies the whole laptop to D:\Backups\Full Backup...tib
1 copies the SD card (always the E: drive, permanently attached to the laptop) to D:\Backups\SD Card...tib

The 2 jobs are necessary because there is no way to get the full backup to include the SD card.  Yes, it's removable.  No, it's never removed.  Its drive letter never changes.

This isn't a big deal in practice, but the issue is that I can't get the incremental backups to work.

Every time I connect the backup drive (always D:\), Windows can see it and Acronis can see it.
But Acronis complains that I need to attach the USB drive.  The backup repeatedly fails until I click the button to change the destination.

I've tried unchecking the "Ask for removable media" option, and I've tried moving the backups into individual subfolders (D:\Backups\OS\ and D:\Backups\SD Card\), but that doesn't work.

Just now, by luck, the SD card backup performed an incremental backup.
But the main backup task refuses to.  In 6+ months I've only gotten the incremental backup to work once for it.

Brian, please download the MVP Log Viewer tool from the Community Tools link in my signature and check what actual messages are being written in the backup logs for your two tasks going to the D: drive?  Post the logs here as text files if you want us to review them with you.
