Configuring saveset expiry options

NetVault Backup supports generation- and time-based retirement methods for backups. You can specify these options in the Backup Advanced Options Set. If the backups are stored on tape media, you can also use the Change Expiry method to set or change the expiry date or generation count later.

This section describes how to set the retirement age or maximum generation count for one or more savesets on physical or virtual tape media by using the Change Expiry method. For more information about the Backup Life option, see Setting backup retirement options.

If a backup has any dependent backups, you can choose to do the following:

•
Defer the removal of savesets until all dependent backups are ready for retirement
•
Force removal of savesets according to their schedule

For more information about backup retirement methods and retirement rules, see Backup retirement.

To configure saveset expiry options:
1
In the Navigation pane, click Explore Storage.
2
Click Explore Tape Storage.
3
In the list of media items, select the tape, and click Explore Media.
4
In the saveset list, select one or more target savesets, and click Change Expiry.
5
On the Media Management - Change Saveset Expiry Date drawer, configure the options described in the following table.
 
Table 109. Change saveset expiry period
Option
Description

Change Expiry Date

To configure time-based retirement, select this check box, and do one of the following:

•
Select the On option, and type or select the date and time in the respective boxes.
•
Alternatively, select the Never option to retain the backup indefinitely.
NOTE: In time-based retirement, the time component (HH:MM) does not represent the actual retirement time. It only represents the time due for backup retirement. The actual time of retirement is determined by the interval at which Media Manager scans the Media Database to identify the backups that it needs to retire. The default interval between two scans is 60 minutes. Thus, if the retirement time is set to 10:20, the backup is actually retired at 11:00. You can change this default setting in the mediamgr.cfg file. For more information, see Configuring default interval for backup retirement scans.

Change Generation Cycle

To configure generation-based retirement, select this check box, and do one of the following:

•
Select the Discard after option, and in the associated box, type or select the number of Full Backups.
•
Alternatively, select the Never option to retain the backup indefinitely.

Force Expiry

By default, if a backup has any dependent backups, its retirement is deferred until all dependent backups are ready for retirement.

You can select this check box to retire a backup according to its retirement schedule. Forcing this behavior can cause early retirement of dependent Incremental and Differential Backups.

To apply this rule globally to all backups, you can modify the Media Manager settings. For more information, see Configuring retirement rules for dependent backups. If the Retirement Timing Control option for Media Manager is set to Force Always, the Force Expiry is option is used, regardless of state of this check box.

c
Click Apply to save the settings.
 
* 
IMPORTANT:  
•
If you set both Change Expiry Date and Change Generation Cycle options for a Full Backup, the backup is retired only when both conditions are met. For example, if you set the Discard After Full Backup Count option to four Full Backups and the Discard After option to 30 days, the backup is retired after four Full Backup counts and 30 days.
•
When a backup stored on a disk-based storage device (such as Quest DR Series system, NetVault SmartDisk, or Data Domain System) is retired, that backup is deleted from the device. You cannot import the deleted backup by scanning the device.
To configure saveset expiry option from Create Restore Job page
1
In the Navigation pane, click Create Restore Job.
On the Create Restore Job — Choose Saveset page, the saveset table provides a list of available savesets.
2
Select the saveset to change the expiry date and time.
3
Click the set expiry date and time, against Expiry field.
4
Configure the options available in Media Management - Change Saveset Expiry Date page. See, Table 109.

Expiring all savesets on disk-based storage

This task describes how to expire all savesets that are stored on disk-based storage.

 
* 
CAUTION: Expiring all savesets removes ALL data stored on the selected device.
To expire all savesets on disk-based storage:
1
In the Navigation pane, click Explore Storage.
2
Click Explore Disk Storage.
3
In the repository table, select the device, and click Explore Repository.
4
On the Explore Disk Storage Repository page, select the saveset, and then click Expire All.
5
On the Expire All Savesets modal, enter the password for the device, and then entire the word EXPIRE to confirm the action.
6
Click OK.

Deleting savesets from disk-based storage devices

Deleting a saveset from a disk-based storage device involves removing its index from the NetVault Database and deleting that backup from the device. You cannot import the deleted backup by scanning the device.

If a backup has any dependent backups, you can choose to do the following:

•
Defer the removal of savesets until all dependent backups are ready for retirement
•
Force immediate removal of the savesets
 
* 
IMPORTANT: Regardless of your selection here, if the Retirement Timing Control option for Media Manager is set to Force Always, the savesets are removed immediately. For more information about this global setting, see Configuring retirement rules for dependent backups.
To delete savesets from disk-based storage devices:
1
In the Navigation pane, click Explore Storage.
2
On the Explore Storage page, click Explore Disk Storage. In the repository table, select the device, and click Explore Repository.
3
To delete multiple savesets:
a
In the saveset list, select the savesets that you want to delete.
To select consecutive items, hold down the Shift key while clicking with the mouse button; to select non‑consecutive items, hold down the Ctrl key while clicking with the mouse button.
b
Click Remove Savesets.
c
In the Remove Saveset dialog box, select the Remove all duplicates associated with selected saveset(s) check box if you also want to remove the Duplicates of the selected savesets.
d
Under Select removal timing option, specify whether you want to force immediate removal of the savesets or defer the removal until all dependent savesets have reached their retirement date:
•
Mark for removal: Use this option to mark the selected savesets for removal. If no dependent Incremental or Differential Backups exist for a saveset, the saveset is removed immediately. If any dependent Incremental or Differential Backups exist for a saveset, the saveset is removed only after all dependent backups have reached their retirement date.
•
Force immediate removal: Use this option to remove the selected savesets immediately. The dependent Incremental and Differential Backups that exist for the selected savesets are also removed immediately, even if these backups have not reached their retirement date.
e
Click OK.
4
To examine a saveset before deleting it:
a
In the saveset list, select the saveset that you want to delete, and click Examine Saveset.
b
Click Remove.
c
In the Remove Saveset dialog box, select the Remove all duplicates associated with this saveset check box if you also want to remove the Duplicates of the selected saveset.
d

Deleting savesets from tape-based storage devices

Deleting a saveset from a tape-based storage device essentially involves removing its index from the NetVault Database. You can still scan the media to import the backup index into the NetVault Database, and use the backup.

If a backup has any dependent backups, you can choose do the following:

•
Defer the removal of savesets until all dependent backups are ready for retirement
•
Force immediate removal of the savesets
 
* 
IMPORTANT: Regardless of your selection here, if the Retirement Timing Control option for Media Manager is set to Force Always, the savesets are removed immediately. For more information about this global setting, see Configuring retirement rules for dependent backups.
To delete savesets from tape-based storage devices:
1
In the Navigation pane, click Explore Storage.
2
On the Explore Storage page, click Explore Tape Storage. In the list of media items, select the tape, and click Explore Media.
3
In the saveset list, select one or more savesets that you want to delete, and click Remove Savesets.
