ATI 2021 - failed (repeated) backup with USB drive
I am testing a scheduled backup to an external USB drive, which is not connected to the PC when the backup is executed.
When the backup fails due to the disconnected USB drive, I get an appropriate message (*) on my desktop and then immediately attach the drive. However, a subsequent backup attempt is not performed, although “Repeat attempt if a backup fails” has been selected under “Options / Advanced / Error handling” for the backup job.
(*) "The backup failed: Ensure that destination 'F:\' is accessible and try again"
Steve, the USB drive was recognized by the system within 15 seconds after the warning message (as I was waiting for it).
And I set the retry setting to 5 attempts, with a time interval of 1 minute between the attempts, which should be altogether more than sufficient. I have no idea whether at least one attempt was tried.
The log files may help show if any reattempts were made or not?
Download a copy of the MVP Assistant log viewer tool and use this to look at the logs to see if they show any issues during the operation process?
The latest version of the new log viewer tool is at the link below.
MVP Assistant update for Acronis Cyber Protect Home Office (Version 1.1.6.0)
If you have Disks & Partitions backups created on ATI 2020 or later using .tibx files, then look in the Backup Worker logs.
If you have Files & Folders backups using .tib files (or Disk backups from earlier versions using .tib files) or using Cloning then look in the Demon logs.
Other logs are shown by the MVP Assistant under the 'Active Logs' heading of the Log Viewer page of the Assistant.
The Schedule2 log contains information related to scheduled task but is one of the more difficult logs to read / work through.
The log files should be zipped to preserve their original file names if sharing in the forums and would need to be less than 3MB in size, otherwise you would need to share the zip file via a Cloud share service such as OneDrive, Dropbox etc.
Thank you for your suggestion. The log's content is in the attached screenshot.
To my surprise, the warning message, which indicated the missing USB drive, was issued only after completion of all five backup attempts at 10:05:35. I would have expected it already after the first attempt.
It seems as if Acronis doesn't recheck the status of the USB drive after the task has started and already found it to be not available!
The approach that I have used is having a Pre Command to check for the drive and abort the task if not found. I have used this for my NAS backups to stop them trying to run when not at home / on my home network.
CheckDrive.BAT
echo off set desktop=%USERPROFILE%\Desktop\USB_Drive.txt set usbhdd="S:" set loopcount=5 if not exist %usbhdd% goto loop :exitloop if not exist %usbhdd% goto nodrive dir %usbhdd% >> %desktop% echo "Drive found!" >> %desktop% exit /b 0 :nodrive echo "Drive not found!" >> %desktop% exit /b 1 :loop set /a loopcount=loopcount-1 if %loopcount%==0 goto exitloop dir %usbhdd% >> %desktop% timeout /t 5 goto loop
Thanks, I will look at your solution.
I did some further tests, now with attaching the USB drive while ATI performs the repeated backup attempts
- the USB drive got detected and the backup performed, which looked positive at first glance
- HOWEVER: the backup does not generate another increment (as per the settings), but replaces the originally created full backup version
I just addressed these issues to Acronis per mail, as ATI 2021 is not supported regularly anymore, assuming that this is a major design flaw affecting more than ATI 2021 only.
Steve, the code you provided can‘t be used as “Pre Command” (included under Options / Advanced), because the result of the check, whatever it is, has no impact on the subsequent execution of the backup, which will be performed whatsoever.
However, it is a good base for an alternative approach, which suits my needs. The solution is, to not start the backup as per the scheduler, but with a command, which is embedded in the bat/cmd-file.
The details for that command (“How to run backups from Command Line”) can be found here:

I too have this same problem. Even attempts to manually run the backup days after the initial failure (because the drive was not attached) gives the "destination unavailable" error. It seems there should be a TI log/data file or some such which TI 2021 consults that could be deleted / edited short of uninstall / reinstall after deleting all TI reg keys, directories / files left after the uninstall.
