Introduction
Prerequisites and Limitations
Chapter 1 17
Limitations The integration-specific limitations are the following:
• The writer’s data must be on an NTFS filesystem.
• The VSS integration backup of writers which store their data on
network shared volumes is not supported.
• With EVA provider, if there are too many source volumes selected for
backup (more than four), it may happen that the creation of
snapshots takes too long and VSS fails the snapshots creation
process. Therefore it is strongly recommended to not select too many
objects in a backup specification because they might reside on more
than four source volumes. This means that for example a Microsoft
Exchange Server storage group should not reside on more than four
source volumes and only one storage group should be specified for
backup in this case. The same applies to a Microsoft SQL Server
database.
• Dynamic disks (Logical Disk Manager partitions) are not supported.
• GPT disks are not supported.
