Restore Volume From a Dump
Describes how to restore from full and incremental dump files.
About this task
There are two ways to use volume dump restore:
- With a full dump file,
volume dump restore
recreates a volume from scratch from volume data stored in the dump file. - With an incremental dump file,
volume dump restore
updates a volume using incremental changes stored in the dump file.
The volume that results from a volume dump restore
operation is a mirror
volume whose source is the volume from which the dump was created. After the operation, this
volume can perform mirroring from the source volume.
When you are updating a volume from an incremental dump file, you must specify an existing volume and an incremental dump file. To restore from a sequence of previous dump files would involve first restoring from the volume's full dump file, then applying each subsequent incremental dump file.
A restored volume may contain mount points that represent volumes that were mounted under the original source volume from which the dump was created. In the restored volume, these mount points have no meaning and do not provide access to any volumes that were mounted under the source volume. If the source volume still exists, then the mount points in the restored volume will work if the restored volume is associated with the source volume as a mirror.
To restore from a full dump plus a sequence of incremental dumps:
Procedure
-
Restore from the full dump file, using the
-n
option to create a new mirror volume and the-name
option to specify the name.maprcli volume dump restore -dumpfile fulldump1 -name restore1 -n
-
Restore from each incremental dump file in order, specifying the same volume name.
maprcli volume dump restore -dumpfile incrdump1 -name restore1 maprcli volume dump restore -dumpfile incrdump2 -name restore1 maprcli volume dump restore -dumpfile incrdump3 -name restore1
