When performing a MS Exchange server backup, the following error message is received in the backup report:
No. | Type | Timestamp | Log |
* | ... | ... | ... |
* | info | ... | Finished running pre-commands |
* | info | ... | ... |
* | erro | YYYY/MM/DD hh:mm:ss | [VSSDatabaseExpt] VSS_E_FLUSH_WRITES_TIMEOUT |
* | ... | ... | ... |
The message is returned by the MS Exchange VSS writer. It indicates the MS Exchange VSS writer was unable to successfully create a VSS snapshot of the MS Exchange database(s) within the default time period due to high disk activity on the server.
To resolve the issue:
vssadmin list writers |
vssadmin delete shadows /all |
vssadmin resize ShadowStorage /For=C: /On=C: /MaxSize=300MB |
vssadmin resize ShadowStorage /For=C: /On=C: /MaxSize=10GB |
