This is a copy method to execute ETERNUS Disk storage system SnapOPC+.
SnapOPC+ uses the Copy-On-Write method to create a pre-update copy source volume.
Refer to "Perform Advanced Copy" in the
SnapOPC+ can save pre-update data on the copy source volume on a per snap generation (unit of volume replication) basis.
SnapOPC+ is designed in view of its mechanism and features to be used as backups for recovery from software failures such as an
operational error or a software error.
If a copy source volume becomes inaccessible due to any hardware failure, SnapOPC+ session(s) fail making it impossible to read the
data on the copy destination volume.
The snapshot copy (SnapOPC+) is effectively available for:
-
Backups of temporary files used for cascade copy to alternate media such as tape.
-
Backups of file servers and other data less frequently updated.
