Title
Volume Warning: Some volumes have not enough free space -
Description
Please see below for an explanation of Warning signs that may be found next to volumes listed under the Volume section of an Agent's Summary Tab.
For Example:
-
Cause
By design, if volumes have less than 30% of free space, a warning sign will be displayed beside those volumes in the protected system Summary screen. Hovering your pointer over the warning sign will display "Some volumes have not enough free space. Please, pay attention that transfer may be failed for full volumes."

Resolution
This does not affect the backups from failing unless it doesn't have enough free space for it to accommodate a snapshot. VSS snapshots generally require 10 -15 % free space on a volume to take a shadow copy.
This warning can be safely disregarded as long as the backups are completing successfully.
To remove this warning sign, you can extend the volume in size so that it has 30% or more free space. However, in some cases (such as a System Reserved partition), this option may not be possible.
