Administrator's Guide
A backup set is a collection of backed up files from one client,
stored and managed as a single object, on specific media, in server
storage. The backup set contains the client node's active, backed
up files.
Administrators can create backup sets on the server for clients.
When an administrator uses the GENERATE BACKUPSET command, the server creates
a copy of previously backed up, active file spaces that are specified with the
command and stores them on sequential media. Clients can restore their
data from the backup sets, without the use of a server. For details,
see Example: Generating a Client Backup Set.
There are benefits to generating backup sets for a client node. For
example:
- Administrators can create periodic backup sets for clients that require
various files be kept for long periods of time. These backup sets can
be written to media that clients can later use to restore their data, without
using network resources to transfer the data.
- Client nodes can restore their backup sets from the server, as well as
directly from the media to which the backup set was written. More
importantly, if the server is not available, clients can restore their data
directly from the media rather than waiting for the server to be
recovered.
- Backup sets can be copied to portable media such as tapes. The
media containing the backup set can be shared with other client nodes or
servers.
- A backup set that is generated on one server can be easily moved and made
available to a different server. Client nodes can restore their backup
set on servers other than the one on which the backup set was created.
