Use the Housekeeping Statistics to check the status. • OK means that housekeeping has been idle and, therefore, not likely to have been impacting on backup or replication performance. • Warning means that housekeeping has not been idle in the last 24 hours. • Caution means that housekeeping has not been idle in the last 7 days A status of either Warning or Caution requires further investigation because it will be affecting backup and replication performance. Configuring blackout windows Scheduling housekeeping blackout windows to cover the period during which backups are occurring can significantly improve backup performance. Click Edit and enter the appropriate times for each window. Make sure the Apply First Time Restriction box is checked. This ensures the times that have been specified are enabled. If it is not checked, the times are ignored. You may configure a maximum of two windows for each day. Settings apply to all devices on the HP StoreOnce Backup System. TIP: Ideally, housekeeping blackout windows should be set for those times when the HP StoreOnce Backup System is running backup or replication. See the D2D Best Practices for VTL, NAS and Replication implementations for recommendations. Pausing housekeeping Click Pause Housekeeping to pause housekeeping altogether (perhaps while you decide how best to configure blackout windows). This setting applies to all devices, libraries and shares on the HP StoreOnce Backup System. It is not retained if there is a power failure or the HP StoreOnce Backup System is powered down. Housekeeping should not be left in the paused state for significant amounts of time; use it only as a test tool. Shutdown (Administration) This option allows you to shut down the HP StoreOnce Backup System cleanly. It is the only recommended way of powering off the device. If you remove the power in any other way and a host is carrying out a backup or restore, you may lose or corrupt data. Click Power Off and Yes to confirm. WARNING! Before shutting down always ensure that there are no backup or restore jobs in progress and that no future jobs are scheduled to start whilst the system is shut down. If hosts do not automatically reconnect to the HP StoreOnce Backup System when it restarts, you must reconnect manually from the iSCSI Initiator on each host, see the HP StoreOnce Backup System Installation and Configuration Guide. Software (Administration) This page provides information about the software version of your HP StoreOnce Backup System and its build date. It also allows you to upgrade the software and the language pack. Whenever 88 Administration

•
OK means that housekeeping has been idle and, therefore, not likely to have been impacting
on backup or replication performance.
•
Warning means that housekeeping has not been idle in the last 24 hours.
•
Caution means that housekeeping has not been idle in the last 7 days
A status of either Warning or Caution requires further investigation because it will be affecting
backup and replication performance.
Configuring blackout windows
Scheduling housekeeping blackout windows to cover the period during which backups are occurring
can significantly improve backup performance.
Click
Edit
and enter the appropriate times for each window. Make sure the
Apply First Time
Restriction
box is checked. This ensures the times that have been specified are enabled. If it is not

You may configure a maximum of two windows for each day. Settings apply to all devices on the

TIP:
Ideally, housekeeping blackout windows should be set for those times when the HP StoreOnce
Backup System is running backup or replication. See the

Pausing housekeeping
Click
Pause Housekeeping
to pause housekeeping altogether (perhaps while you decide how best
to configure blackout windows). This setting applies to all devices, libraries and shares on the HP
StoreOnce Backup System. It is not retained if there is a power failure or the HP StoreOnce Backup
System is powered down.
Housekeeping should not be left in the paused state for significant amounts of time; use it only as
a test tool.

This option allows you to shut down the HP StoreOnce Backup System cleanly. It is the only
recommended way of powering off the device. If you remove the power in any other way and a
host is carrying out a backup or restore, you may lose or corrupt data.
Click

WARNING!
Before shutting down always ensure that there are no backup or restore jobs in
progress and that no future jobs are scheduled to start whilst the system is shut down. If hosts do
not automatically reconnect to the HP StoreOnce Backup System when it restarts, you must reconnect
manually from the iSCSI Initiator on each host, see the HP StoreOnce Backup System Installation
