We are trying to backup our On Premise W2K12 R2 file server drives to Azure using Azure Recovery Services. But the backup fails with below error.
Microsoft Azure Backup failed to access the shadow copy because of inadequate disk space on the volume. Retry the operation after increasing the free space available in the volume (0x08174)
Can someone help me on this. Also, please have a look on the screenshot.
How large is the backup? It will create the scratch directory locally on the C drive by default, which requires 10-15% of the total backup size.
You may be out of space on the volume where the scratch directory is located.
