BackBox H4.00 User Manual

Product Description
21 BackBox H4.00 User Manual
A virtual volume just written is unloaded by the NonStop
server (new Windows files to backup)
A virtual volume must be loaded for the NonStop server
and a corresponding Windows file is missing (Windows
file to restore)
Scripting facilities
Scripts are identified in the Data Store advanced configuration page. User
parameters can also be defined and their value set in the same page.
There are two sets of scripts.
The first set corresponds to a simple setup, where a script is executed for each
virtual volume.
The second set is used when scripts are run by the Script controller. In this case, the
scripts named in the Data Store advanced configuration just forward the backup or
restore request to the VTC Script Controller. The Script controller manages queues
of backup or restores requests and submits actual backup or restore scripts that can
process several virtual volumes in the same execution.
The Script controller is a batch sub-system and is used for two reasons:
• Retries: When the user wants another layer of error recovery on top of
whatever retries the Enterprise Backup clients implement. By default, the
Script controller will retry for 24 hours, with a delay of 5 minutes before a
retry.
• Serialization: A VTC typically implements several virtual tape drives and
might trigger several concurrent scripts. The number of concurrent script
executions might be limited by the Enterprise backup software, or just
because the Enterprise backup client writes directly to a physical tape library.
The script controller queues the backup or restore requests, consolidate
similar requests together and submit them in a number of queues and
threads per queue set by the user.
Disk space management tools
The “Windows Storage Admin” page in the BackPak user interface shows a summary
of the Windows Data Store disks.
This page shows the summary from different groupings and allows the user to
resubmit the backup script for all Windows files that have not been backed up for
any reason including when a new backup script has just be configured.
BackBox provides TACL macros that can be scheduled in NetBatch to:
• Delete files corresponding to volumes expired in TMF or DSM/TC catalogs. If a
delete script is configured, it will be executed to delete also the backup of the
expired file. (BB017_FREE_EXPIRED)
