Introduction

When a backup ends with an error status (backup is not created), Acronis True Image displays a short error message in the product interface, and writes the details in a text log file (“full log”).

This is a split backup, and the last volume of it is missing; The backup that you are trying to delete is corrupted. Use the Remove from the list option to remove the backup from Acronis True Image Home 2012: Delete the backup manually from the network location if necessary. More information. See also Acronis True Image Home 2012. Acronis True Image Home 2010 provides home users reliable and timeless backup and recovery of their operating system, applications, settings and personal files. Friendly, Windows®-style User Interface.From an intuitive graphical interface, you can easily define where, locally or online, and how often to backup a PC based on your needs.

To see the short error message do either of the following:

Click on the red cross or the pause icon || in the center of backup task screen.
Click on the Activities tab of the failing backup task

If the short error message was not enough to find a solution and resolve the issue, search for key words «error» and «failed» in the full log which can be accessed by any of the listed methods:

Locate the newest file at C:ProgramDataAcronisTrueImageHomeLogsti_demon and open it in Notepad
If you have configured email notifications, the full log will be attached or included in the body of the email
Download and launch Log Viewer tool (does not require installation), from https://kb.acronis.com/content/59335. When launched, it automatically loads and displays a formatted log of the latest backup attempt, where you can find the error message and look it up here.

Before you begin

If you do not want to troubleshoot, but are OK with repeating the procedure of configuring the backup task and running a full backup again, you can try a clean reinstall and start over with a new backup task. Create a new empty folder in the backup destination for storing the backups (local backup) or create a new backup task (backup to Cloud). Delete the old backup to make room for the new backup. While that does not help always, it still can save you time and efforts on troubleshooting a number of backup failures, especially undocumented.

Common backup errors, causes and solutions

Backup error message For causes and solutions please see the entire cells to the right.	Possible causes	Solutions: apply solutions in the order they are listed. Check if the issue is resolved after each.
The device, where backups are physically stored, is powered off, not connected, hung up or does not provide access to the directory with backups due to any other reason Multiple drives are used either for storing backups, or as backup source, within a single backup task. Acronis True Image does not support rotating drives The folder where backups are stored changed its name, was moved, deleted or user permissions for accessing it changed A parent directory in the folder hierarchy changed its name, was moved, deleted or user permissions for accessing it changed Backups to local network/NAS: Location for storing backups was defined using the IP-address (e.g. “192.168.0.12backups”, it changed after updating the software/firmware of the NAS Location for storing backups was defined using the name of the NAS/network device (e.g. “MyCloudbackups”, and an issue on the router, NAS or the PC/Mac caused the network name to work anymore (e.g. you can access files and folders on your NAS by IP, but not by name) .TIB files were renamed, moved or deleted outside of Acronis True Image interface Outdated names, paths or access details in the cache of Acronis True Image .TIB files were renamed, copied, moved or deleted outside of Acronis True Image program’s user interface: have you cleared up disk space by deleting .TIBs in Windows Explorer? Now the old paths to .TIBs, remembered by the program previously, point nowhere and the software is unable to access the files required to continue a backup set.	If backup source or destination drives are swapping/rotating external USB disks: create one backup task for each source and each external drive or switch to Acronis Backup 12.5 (PC, Mac) Bitlocker-encrypted disks: unlock the disk where backups are stored, see https://kb.acronis.com/content/58859 for details Edit backup task and reselect backup source and destination Follow https://kb.acronis.com/content/60612 NAS: reboot the NAS Repair program settings as per https://kb.acronis.com/content/60915 Clean reinstall Acronis True Image: https://kb.acronis.com/node/60195/#Clean_install2

The drive is not ready		The disk device is not responding properly to read/write requests, which could be a temporary glitch or a permanent failure of the device - try copying a file from the selected backup source to the backup destination using Windows Explorer to check that factor Corrupted file system or disk partition table Acronis drivers for accessing the disks are not functioning properly	Reconnect external disk: Safe eject the drive If it has an external power source – disconnect it, wait 10 seconds, and re-connect it Re-connect the disk to a different port on the computer NAS devices: reboot the NAS Reboot the computer. If the check of copying file through Windows Explorer failed (see the “Possible causes” part to the left) Repair software installation: https://kb.acronis.com/content/60195#Running_the_update_repair_installation1 , then edit backup task and re-select backup source and destination Change the caching policy for the disk to “Optimize for quick removal” as per https://kb.acronis.com/content/4071

As a result, the new/extended license was not activated and the software moved into trial mode. Renewed subscription license was activated to a different email address, leaving the original account without a license. Software entered trial mode, which then ended. The regular license check failed and the software transitioned into trial mode, which then ended Renewed subscription license or a new perpetual license could not be activated due to any other reason, the software entered trial mode, which then ended System date and time changed as a result of system recovery, clone or any other way Issue with the license cache on the current computer	Check the major version of installed Acronis software (e.g. 2014, 2018), remember if you have trialed it before on the current operating system If you have a non-trial license: activate it as per https://kb.acronis.com/ati2018/activation Subscription users: make that the new license is registered to the same Acronis account.

Disk is full		Running out of space on the disk where backups are stored: Automatic backup cleanup does not apply to backup versions that are not visible in Acronis True Image interface. As a quick check, open “Recovery” dialog and expand the list of available dates – recovery points, compare to .TIB files Automatic cleanup rules are misconfigured Earlier backup versions were not deleted due to any reason The disk where backups are stored, became filled with not Acronis files NAS: the limit (quota) for the NAS user account, indicated during backup setup, has been reached. This quota/limitation is configured in NAS settings outside of Acronis software. Acronis has no influence on it. The NAS user account is completely unrelated to Acronis account and is set exclusively through the NAS management panel External drive, where backups are saved, has quotas enabled for different Windows users. To check if that is the case, right-click the disk in Windows Explorer, click on the Quota tab and click “Show Quota settings” Not enough free disk space on the source disk for Microsoft VSS snapshot Too high disk activity on the source disk causes Microsoft VSS snapshot to cancel and delete	Check that other software is not filling the disk space where you save the backups. Move or delete the files from other software to a different disk/location If there are .TIBs that are not registered in Acronis True Image (missing in the list of recovery date/time), turn off self-defence feature as explained at https://kb.acronis.com/content/60190 and delete these orphaned .TIBs from the destination disk. If you need those backups – add them to the list as per https://kb.acronis.com/content/60918 and find what other backups/backup versions to delete to free up disk space Correct the rules for automatic backup deletion and free up disk space: Enter backup settings – tab “Backup scheme” and adjust cleanup settings: reduce the number of backup chains to keep (a backup chain is a full backup and all the incrementals/differentials before the next full backup). Earlier backups are deleted by chains. Deletion of any backup version is postponed until all the chain is subject to deletion. Free up disk space by deleting backups: click the arrow key next to backup name in Acronis True Image to open the menu, choose “Delete” – “Delete entirely” or “Cleanup versions” Close all other programs when running the backup, especially antivirus, security and software that could be intensively reading or writing data to disk: data synchronization, copying, backup, cataloging, search and indexing Run the free Acronis tool for troubleshooting Microsoft VSS issues: Acronis VSS Doctor.

Hello ATI2018 Forum,

Trying to do a partition (win10 C) backup to my Synology NAS as a scheduled backup. If I run it manually it works fine. Verification of the backup also works fine. I do scheduled validation once per month and am trying to do scheduled backups once per week.

I have run a 'clean' disk check on the drive. Win10 nor does WD utilities see any errors on the disk.

All that said, why do I get failures?

There shouldn't really be any difference in backup operation between running the same backup task manually or letting it run by schedule. The only obvious difference is that the manual task is running under your own user account profile, whereas the scheduled task is running under the account that was used when ATI was installed - which should be an Administrator account.

One option that you could try would be to try running the scheduled task using the Windows Task Scheduler via a batch file instead of using the Acronis Scheduler.

::RunATITask.bat

Acronis True Image Home Backup Archive File Is Corrupted Sd Card

echo off
set ATI='C:Program Files (x86)AcronisTrueImageHomeTrueImageHomeNotify.exe'
set task=2BF45C62-B17B-4816-B470-9825BDCDC572
%ATI% /script:%task%
exit

See KB 47143: Acronis True Image: How to run backups from Command Line for more details on how to find the correct task identifier to use.

Another option would be to test the same backup task to an external USB drive instead of to your Synology NAS to see if the destination has any bearing on the error? Again, this shouldn't be so - I run regular backups to my own Synology NAS by schedule without issue!

Thanks for the insights Steve!

ATI was installed by me under my admin level account on my Win10 PC. Also 'funny' is that I have three other (total of four) backup scheduled backup jobs that now run without issue. They are all of different folders on my Synology NAS and the backup files are stored on a 2nd (D:) internal HDD on the same Win10 PC.

I ready in one of the older ATI2015/16 posts that the same error message could be related to what ATI believes is an issue with the source HDD, but I have run a few different disk checks & tools and none report any errors on the drive.

I also run all my backup jobs on different days to help ensure there are no competing tasks that might clash with each other. Are there any additional logs or debug level commands that can be enabled in ATI to help provide more info?

Over the next few days I will try a series of tests (including your suggestion about using the Windows scheduler) to see if i can further ID the issue.

### UPDATE ####

In checking things out I discovered occasional slow response from my Synology NAS. Checking this out, i found that the disk utilization was pegged at 100%. A few google searches later I found that others had issues with the Synology AV service running and causing high disk utilization & other performance issues. I even had to hard boot my NAS to regain access to the management interface but once in I removed the scheduled AV scans (not sure where those came from).

I re-setup all my ATI backup jobs and ran each manually to be sure they worked. I have also re-enabled the backup schedule and the first two jobs ran without issue. What appears to have been the issue is that the other NAS disk activity may have been occasionally higher when the backups were running over night. No one ever noticed any file access issues during the day so I never considered the issue might be the NAS.

Will update in a week or two as to how things are progressing.

Thanks for sharing the update about the AV scans on your Synology NAS - have been checking my own and checked the AV settings there!

### UPDATE ####

Life has been much better since disabling Synology AV. Again, Not sure how or when that went sideways as its been months since I even touched Synology. I will add that in late OCT, i lost my primary WIN10 HD and had to try to recover from ATI backup. While the files were located on my Synology share, there were issues with the backup files and was not able to do a clean recovery. I had to re-install ATI2018 and re-add the backup jobs ..... and here we are today.
