You mount a network share as a Windows mapped drive in Windows Explorer or through the net use command. When you use Acronis software, you may observe the following:
- Mapped drives are not listed/available in GUI (e.g. as the backup source/destination).
- Backup via acrocmd command line tool to a mapped drive fails.
- The drive letters of the network drives are displayed, but it is not possibe to access the content.
Windows mapped network drives are not supported as they are mapped on a per-user basis and are not available for built-in accounts such as Local System or Network Service. This restriction is built-in to Windows at the operating system level.
When you map a network drive, it becomes mapped only under a respective Windows account on the local machine - and thus it is not accessible to Acronis services executed in the context of the system account.
Use UNC path to specify a network share:
When using bootable media, always specify the UNC path to access the network share.
