If there is an issue with backing up a NAS unit, try using shorter folder names

You can only back up files or folders which are on a NAS unit. There is no possibility to back up the whole hard disk drive or partitions of a NAS unit.

When selecting Items to back up switch to Files view and browse Network folders of specify Path to your NAS:

In Acronis True Image 2018 and later you can select your NAS as a backup source, and then specify files and folders that you want to back up:

Solution

From a computer, using the Acronis product run the backup wizard and browse to the network share and select the files to back up.

For Acronis Cyber Backup, the share/NAS that you want to back up must be accessible from the selected machine.

If there is an issue with backing up, try the following workarounds:

  • Reboot the computer with Acronis software, router and NAS to reset network connection to NAS. Close all other programs that might be using files on NAS before Acronis backup begins, e.g. other backup and synchronization sofware, programs with media and other types of catalogues (databases, pictures, music, videos) that might be updating and locking files on NAS.
  • If you have the NAS unit mapped, please unmap it;
  • Create shorter folder names (e.g., less than eight characters in a name) on the NAS. The product may fail to recognize longer folder names;
  • Try disabling authentication on the NAS (i.e., grant everyone access to the drive).

More information

File-level backup means that snapshot is not created during backup. A snapshot is a technology that allows user to make changes to the system while it is being backed up, e.g. open files and add new information or delete files. Acronis software uses snapshot while backing up disks. In case of a file-level backup snapshot is not created, which means that files in use will not be backed up. We recommend scheduling NAS backup for the time when files on the NAS are not in use.

If there is an issue with backing up files on the NAS unit, please contact Acronis Support with a reference to this article and the following diagnostic information:

  • AcronisInfo Utility;
  • NAS model and version;
  • Logs of the NAS (usually can be accessed from the NAS management portal);
  • Date and time, when the issue occurred;
  • Any illustrating screenshots;
