NetWorker 19.7 Snapshot Management Integration Guide

File systems

The file system, database, or tablespace name should be the same as the source saveset.

Any additional FS/files/directories must be added to the psrollback.res file.

LUNs

The number of alternate host LUNs should be the same as the number of LUNs at the time of backup.

Size:

• For SnapVX, the size of LUNs should be equal to or greater than the size of the backup LUNs.
• For ProtectPoint, the size of the LUNs should be equal to or greater than the size of the static image.

Volume Groups

The volume group name can be different from the source saveset.

Can be any size.

Logical volumes

The logical volume name can be different from the source saveset.

The number of logical volumes on the alternate host can be equal or less than the source saveset.

If the logical volumes on the alternate host are greater that logical volumes in the source saveset, then you should add them to the psrollback.res file.

Can be any size or layout.

Host

Alternate LUN Rollback is supported only on a destination host other than the source host.

Array

Alternate LUN Rollback is supported only on Snapshots that are taken on SnapVX and ProtectPoint SnapVX.

SmartSnaps

While Rolling back a Smart snapshot to a destination host, the rollback is done to any destination LUN which was specified in the "NsrSnapSourceSG" Storage Group. By default, the system selects LUNs visible to the destination host. To select any LUN, visible or not visible, specify SELECT_HOST_VISIBLE_TGTS=false.

Additional affected file systems that are not a part of the rollback will not be mounted or unmounted.
