nsrclone

The nsrclone program makes new copies of existing save sets. The operation is automatic when you enable the Clones attribute of a NSR group resource. You can also run nsrclone on a manual basis from the command line.

Although the command line options enable you to specify a volume name or identifier, nsrclone always copies complete save sets, regardless of how many volumes the save set components reside on. The nsrclone program does not copy volumes; instead, it copies the original save sets specified from one volume to a volume assigned to a special pool for clones. If the first destination volume cannot hold all the save sets to be cloned, another volume from the same clone pool is chosen.

If you use the -c and -N options together, nsrclone creates a super-full copy for the given client save set. The super-full copy is a feature that is supported only under HSM. It automatically creates a clone of the most recent complete full backup of the named client and save set, along with any HSM migration save sets referred to by the full backup. Super-full copies should be cloned to a volume from a migration clone pool. If no migration save sets are referenced by the most recent full backup, only the full set is cloned.

The nsrclone program, in cooperation with the nsrmmd daemon, guarantees that each save set has only one clone on a given volume. When you specify a volume name or identifier, the copy of the save sets on that volume are used as the source. When you specify save sets explicitly, those with existing multiple copies are automatically chosen; copies of save sets that exist on volumes in an autochanger or silo are chosen over those that require operator intervention. You can also specify which copy of a save set to use as the source, with the -S option.

The following example describes the format and options available for the nsrclone program:

nsrclone [-v] [-s server] [-b pool]

{-f file | volume-name}
nsrclone [-v] [-s server] [-b pool] -S

{-f file | ssid}
nsrclone [-v] [-s server] [-b pool] -V

{-f file | volumeid}
nsrclone [-v] [-s server] [-b pool]

-c client -N saveset

• Use the -b pool option to specify the name of the clone pool to which the data should be migrated. If you omit this option, the cloned save sets are automatically sent to the Default Clone pool.

• Use the -c client option, in conjunction with the -N option, to specify a client whose save sets should be considered for a super-full copy.

• Use the -f file option to instruct nsrclone to read the volume names, volume identifiers, or ssids from the text file specified.

• Use the -s server option to specify a Backup server to migrate save sets from. If you omit this option, the current machine is selected by default.

• Use the -S option to specify one or more specific ssids. You can issue the mminfo -v command to determine the value to use for ssid (see "mminfo " for details).

• Use the -v option to run nsrclone in verbose mode. This mode provides additional information during the process, for example, messages about save sets that cross volumes.

• Use the -V volid option to specify the name of the volume.
