The TSA packages data from the target and presents it to the SME in a generic
format. This allows one SME to interact with many types of TSAs.
NetWare 6 provides TSA600.NLM, with the following features:
 Supports backup and restore of traditional NetWare file system and NSS
file system
 Supports backup and restore of cluster-enabled pools (see “Backups and
Clusters” on page 29)
 Recovers the backup session in failover and failback conditions
 Provides the caching feature for optimizing backup performance (see
“Customizing Backup” on page 53.) The TSA will scan the data sets prior
to the engine request and commit the data set information to the cache.
When the request comes in, the data is read from the cache instead of from
the disk
NOTE: To use this feature, ensure that your backup engine supports the scan-
ahead option. If the option is enabled without appropriate changes to the engine,
unexpected results may occur. Also note that performance might vary from engine
to engine.
Restore Services
Restore services provides information on how SMS restores data from
eDirectory, volume SYS: and other volumes, single servers, multiple servers,
and the eDirectory tree structure.
Use SBCON to retrieve and reinstate data you have backed up to storage
media. You restore data if it has been lost or corrupted since a backup was
made.
A restore session restores data from a backup. The restore session produces
the requested data, which is retrieved from the storage media and restored to
the location you specify. If an error occurs during the restore session, an error
message is appended to the error file on the host server.
