"The backup cannot be started. Make sure that the destination G:\ is accessible and try again." ??
Just obtained a brand new Dell Optiplex 5090 desktop PC (Win 10 Pro) and set it up for my wife. I am using an nvme main drive (EVO 970 Plus) and have two external USB 3.0 drives connected for backup. Installed the brand new Acronis Cyber Protect Home Office.
Backups at first successful, but now I am getting the error in the title when I try to back up. I have re-designated the destination drives in the backups, deleted the backups and re-created them, and UNINSTALLED AND REINSTALLED Acronis twice, including with the cleanup tool, thinking that would clear the apparently incorrect disk identifiers. On the most recent reinstall, I was able to obtain one sucessful backup (nvme disk to usb disk), but after a restart, I am getting the same error with both USB disks as destinations.
I have used ATIH for many years. Used the same USB drives for backup with wife's older Dell, and use it myself on Macs and PCs - never had this issue.
What I don't understand is why completely removing the software doesn't result in rebuilding of the disk database.
Tried to view the logs but with the new log viewer, had trouble figuring out what to look at.
Program should just work - tech support tickets are a great deal of time and work.
Any ideas? Thanks!
That's not it. Drive letters correct and unchanged.
The new Dell PC replaces a similar but way older one, and the USB external backup disks had Acronis backups of the old PC on them. Even when I did not add them back to the new Acronis installation, I am suspecting that the program finds the disk database stored in old backups, and then looks for the old UUIDs. Same external disk controllers and disks, but a new PC with new registry - so it doesn't find them.
I tried uninstalling the external backup disks in Device Manager, and formatting the backup disks- same error.
What may have worked (so far) is eliminating all references in the Device Manager, with "show hidden devices" enabled, to USB disks and controllers not currently mounted.
Over my head, and I'm failry knowledgeable - I just wish Acronis provided a way to clear its disk database!
Sorry but as far as I understand there is no such disk database held by Acronis that can be cleared!
In the same way, the backup image files stored on your external disk drive also have no UUID information stored within them to identify the drive they are stored on.
If the external disks just have backups of the old PC stored on them, then what are you wanting to do with these in this context? If these are purely kept for reference and not going to be used then they do not need to be listed in the Acronis GUI as you can explore any of the .tib or .tibx files from Windows Explorer by double-clicking on them.
The script files for backups do contain a partition UUID. Using the MVP Assistant, you can inspect the script files in the "Acronis Configuration" section. The "System Configuration" section will also allow you to inspect the drives and partitions and see the UUIDs there as well. In my case where I back up to a fixed drive I can see the matching UUIDs.
I was about to suggest removing the USB devices in Device Manager but I see you already have and it was of no help.
Agreed Bruno about the script .tib.tis files for tasks configured in the main GUI but this is not included in the backup image as such on the storage drive so if the backups have been added as existing backups to create tasks in the GUI, the UUID information would be taken from the Source selection the user made when reconfiguring the task(s).
If new tasks have been created for the new PC, then reselecting the Source and Destination should resolve this type of issue if the UUID's change because of installing a Windows Upgrade such as 21H1 etc.
My goal is to have my nightly scheduled automatic backups work! They are not. (total 3 rotating backups of system disk to my 2 USB backup drives),
Yesterday, after some more messing around (I have uninstalled and reinstalled Acronis, removed, erased, formatted backup drives so many times in so many orders that I don't remember exactly what I did), and then was able to sucessfully create a new backup of my system disk to one of the external drives. I then selected one of the backups I had created earlier, and it updated successfully. (All my backups are single version chain).
Overnight, the scheduled backup to the same backup disk failed with the same error - "make sure destination disk is available".
Never had this kind of issue before, really frustrating. Ready to open ticket with Acronis, but that is always very time consuming uploading reports and rarely solves.
The behavior you describe suggests that for some reason your backup tasks are corrupted in some way. I am providing a link to the Schedule Manager tool which can be used to remove backup tasks from the schedule manager service. I would recommend that you remove all backup tasks that the tool lists and start over.
The link will take you to the kb page and provides a download link and usage instructions. For task functions look for the section of the kb titled Managing scheduled tasks.

See KB 62741: Acronis True Image: rotating backup destination disks requires separate backup plans per destination disk - which looks to apply to your chosen backup process!
I'm not swapping disks. I have two separtate USB disks connected, and have different backup tasks scheduled on different days of the week.

Ok, thank you for clarifying the above. In that case I would suggest starting over again here and looking at the logs for these backup tasks to see what is or is not happening here?
There is a new MVP Assistant log viewer tool that has now been made available by Acronis via the Community Tools page..
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 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.
jwitkin,
You backup tasks are all pointed to their own unique folder correct? If not this could explain the behavior.
My backups are on the root level of the backup drives, so the two scheduled backups that go to that drive are in the same folder. That has never been a problem for years.
I may have found solution. With the USB backup drives mounted, I uninstalled them in Device Manager, then restarted (and of course they reinstalled).I then went to my backups in Acronis and re-selected the destination drives. All of that I had done before.
What I hadn't done before was add back the exisiting backups. I saw the warning that previous versions would not be listed in recovery unless they were added back, but since I do a single chain (full erase and copy) backup, I wasn't concerned about the last backup.
Perfectly reasonable that Acronis would look for the last backup it expects to find when initiating a new one (especially if the backup were incrememntal) and would complain if it didn't find it. So "destination disk not available" may have actually meant "last expected backup version not found on destination disk".
So yesterday I DID add back the previous exisiting backups, and last night the scheduled backups worked. We'll see if it continues. Thank you all for your comments.
Glad to hear that the backups worked for you last night. This may no longer be applicable but in the past the True Image backup database would become corrupted if multiple backup tasks were set to use the same folder to store backups in due to naming conventions. So it is recommended that each task use a unique folder location for backup files.
Having said that beginning with the 2020 version of the product metadata tracking of backup files was added which in theory would make the unique folder recommendation obsolete.
OK, after adding an additional file backup, the scheduled system disk backup failed again last night, same error. Uninstalling both backup disks in Device Manager, restarting, re-defining the destination disk in the backup, and adding back the previous backup "fixed" it again.
Really hesitant to open a ticket - requests for support files, 3 days at a time between responses, often asking questions I've already answered... disappointed!
So have you tried creating unique dedicated folders for your backup tasks?
Never had to create separate folders for backups, running Acronis on two other PCs with backups at root level exactly the same with no problems.

It would only really cause issues if you use the same task names for your backups from different PC's, but using separate destination folders is simply cleaner to manage so you know immediately that all the files belong to the same source PC rather than having a mix of files.

I doubt the link below will help you but have a look. It details the most common backup errors and outlines the suggested remedies.
Acronis TrueImage Home 2018 (my previous perpetual license) is working just fine!! :(
Tried rebuilding the database in Acronis in ProgramData folder as one of the KB suggested. No help.
So I unstalled Acronis Cyber Protection with the Acronis cleanup utility.
Uninstalled my two USB backup disks in Device Manager
Reinstalled backup disks and erased and formatted them.
Enabled "show hidden devices" in Device Manager and removed every disk, volume and storage controller that was not currently connected
Reinstalled Acronis Cyber Protection.
Created new backup to the USB drives
GOT THE SAME ERROR when attempting to start the backup - destination drive not accessible.
Something in the registry that is not being deleted when Acronis is uninstalled? PC is brand new Dell desktop, no programs on it that aren't on my other PC on which ACPHB is working fine.
Unable to open ticket on Acronis website - says "please register your product" though I am logged in and my product shows as registered. Requested ticket through the app feedback. Waiting.
Seriously, installed ATIH 2018, working no problems...
I don't need cyber protection, just a good backup program without issues. Thinking of looking elsewhere...not happy.
Have you installed and run ATI 2018 on this brand new Dell desktop with the same drives? If so and it is working then would consider staying with that version and request a refund for ACPHO given you don't need the Cyber Protection features it brings along.
