Backing Up and Restoring Files
Local and Remote Backups
5-5
Note You do not need to format tapes for a backup. However, before you load
tapes in the Autoloader, make sure they are not write-protected.
The length of time required to perform a backup depends on the size of the
volume and the local area network (LAN). As a general rule:
n For a local backup, the Autoloader backs up 25 gigabytes per hour.
n For a remote backup on a 10Base-T network, the Autoloader backs up
3 gigabytes per hour.
n For a remote backup on a 100Base-T network, the Autoloader backs up
10 gigabytes per hour.
During a backup, the Autoloader’s control panel displays Writing and
the green activity light flashes.
Performing a Local Backup
Use the backup application in the NetStorage web interface plus an
optional 818 or 1/9 HP SureStore DLT Autoloader to perform a local
backup. See the installation poster for directions on attaching the
Autoloader to the HP NetStorage 6000 and see “Using the HP SureStore
818 or 1/9 DLT Autoloader” on page 5-1 for information on using the
Autoloader.
Note You can only access Tape Status, Tape Backup, Tape Restore, and Tape
Settings in the Backup/Restore tab after you attach an Autoloader to
your HP NetStorage 6000
In a local backup session, a special checkpoint of your data is first created
on disk, then the data is transferred to the locally attached Autoloader. The
checkpoint uses only a small amount of disk space and the data transfer
does not interfere with your LAN traffic.
To run a local backup:
1 From your workstation, open a web browser and enter the IP address of
the HP NetStorage 6000.
2 Click the Backup/Restore tab, then select Tape Backup (see “Creating
and Executing Backup Jobs” on page 5-14 for more information).
The local backup feature provides simple scheduling capability and can be
configured to back up individual files or combinations of volumes.
