There is a limit on space that must be free on each volume of the backup source. Veeam Agent requires free space to create a VSS snapshot of the backed-up volume. The limit depends on the size of the volume.
Volume Size (MB) | Free Space Limit (MB) |
---|
up to 524 | 52 |
525 to 1073 | 355 |
1074 to 2146 | 525 |
2147 and more | 1073 |
During the backup job session, Veeam Agent checks volumes to ensure there is enough space for the job to run:
- If free space is less than the free space limit, the backup job fails.
- If free space is less than the free space limit multiplied by 2, the backup job finishes with a warning.
For example, if the volume size is less than 525 MBs and free space is 52 to 104 MBs, Veeam Agent finishes the backup job with a warning.
