2 BackBox H4.00 VTC Scripting Option
Archive bit
The Windows file system maintains an Archive bit among other disk file properties.
BackBox expects this Archive bit is reset by the backup script or by the Enterprise
backup software.
When the Archive bit is not reset:
- In the BackBox GUI, the Storage Admin page cannot display the number of files
that are not backed up yet, and the “Backup all non-backed up files” will
backup all Windows files.
- The “Delete backed-up files” (disk staging) cannot be used efficiently.
As bypass to current special conditions of HP StoreOnce NAS, the,
- The Script Controller cannot be used if the successful archiving of a file is not
notified by an Archive bit reset or by a file deletion.
Archive-Bit with a TSM Enterprise Backup
In TSM (Tivoli Storage Manager) for which Archive is recommended over Backup, the
BackBox utility BB_ArchiveBit verifies the successful Archive in the server and then
resets the Archive bit at the end of the backup script.
No Archive-Bit in StoreOnce NAS
To free-up the online storage and keep only the offline copy, the “Delete
backed-up files” processing is based on the Archive Bit reset by the
backup software.
Special conditions make the Archive Bit currently not supported by the HP
StoreOnce NAS. For this storage type, the current way to verify a file has
been backed-up is to restore it.
When a VTC executes BB023_DEL_BACKEDUP ( “Delete backed-up files”)
for a Data store configured as “StoreOnce NAS”, it will restore the file by
the regular restore script to a temporary storage when a file becomes a
candidate for removal from the on-line storage. If the restored file looks
identical to its original, both are deleted.
Directing to different storage services
If there is a need for directing different NonStop backups to different kinds of
storage services inside the Enterprise Backup software, it can be done several ways.
The natural parameter in NonStop OBEY files is using different DSM/TC pools, each
pool being associated to a different Volume Group in BackBox.
Two Windows named parameters depending on the Volume group are available in
the scripts:
