tsaunix -- Storage Management Services (SMS) Target Service Agent (TSA) for UnixWare

Synopsis

tsaunix

Description

The tsaunix program implements the Storage Management Services (SMS) Target Service Agent (TSA) API on a UnixWare machine for the purposes of backing up mounted filesystems. When the tsad(1) program receives a connection request from a SMS backup/restore engine on a NetWare server, it will spawn a tsaunix process to perform the actual backup or restore. tsaunix does not cross mount points and does not traverse the symbolic links while backing up. It does not backup the remote filesystems (for example, NFS®).

The local filesystems are the primary resources and the directory on which a filesystem is mounted is shown as the resource. The leading ``/'' in the mount point directory is shown as ROOT: on the backup engine.

The user can specify the scan control options from the engine to customize how to scan the directories and files to back up. One of the scan control options specific to UNIX is ``Exclude device special files.'' This option is set to ``no'' by default which means that the device special files are backed up in default case.

The user can choose the selection list for filesystems, directories and files for backup and restore. The selection list is specified on the backup engine and is the include/exclude list for filesystems, directories and files.

A default exclusion list (paths that by default will not be backed up) is created from the /etc/Ignore file on the UnixWare system, removing any paths mentioned in /etc/Backup.

The default exclusion list takes precedence over the selection list sent by the backup engine.

The backup data is encoded in System Independent Data Format (SIDF).

Error messages, if any, are written to /var/adm/unixtsa.log.

Files

/usr/lib/locale/LC_MESSAGES/tsaunix.cat
Language-specific message file (see LANG on the environ(5) manual page).

/etc/Ignore
Paths that should not be backed up by default.

/etc/Backup
Paths that should be backed up even if they are implied by entries in /etc/Ignore. tsaunix uses this file only to eliminate the entries common to both /etc/Backup and /etc/Ignore from the default exclusion list.
