Data Protector A.05.10 - ZDB for EVA in the CA Configuration

5.1.3 EVA Mount Options
Dismount the filesystems on the
application system
Select this option if you want the filesystem on the
application system to be dismounted before a snapshot is
created and remounted after a snapshot is created. A
filesystem does not have the stop I/O functionality to flush
the data from the filesystem cache to the disk and stop the
I/O for the time of the snapshot. This option can be used to
ensure that the data on the filesystem is consistent.
By default, this option is not selected.
Enable the backup system in
read/write mode
This option is related to UNIX systems only, since on
Windows systems filesystems are always mounted in
read/write mode.
As CA EVA backup runs on Windows Server 2003 systems
only, this option is ignored.
