Issue



During a backup operation on a deduplication folder that is on a volume that has been extended, the low space threshold is reported incorrectly.


Solution



When the volume where a Backup Exec Deduplication Storage Folder is located is made larger by using the Windows extend functionality, the Backup Exec reports the wrong error when reaching the low volume threshold.  Normally, when the low volume threshold is reached, an alert is generated informing the administrator that the low volume threshold has been reached and that more disk space needs to be made available to the deduplication folder before the backup can continue.

On a volume that has already been extended, a backup continues until it reaches another internal threshold.  The job then fails with the following error:

Error reported:
0x17V-79-57344-34028 - A backup storage read/write error has occurred.

If this error is encountered, check the properties of the deduplication folder.  If the deduplication folder is below the threshold of available free space on the volume, then either more space needs to be made available to the deduplication folder by extending the volume again or by reducing the amount of data that is being backed up to this deduplication folder.
