Applying Incrementals to an HSR Volume

You can use the Restore Wizard to apply incremental files to update an unfinalized HSR volume. Note these cautions:

• You can only apply later incremental images that are "descendants" of the last Incremental image file used to update the HSR volume. (Descendant image files are newer incremental images that are part of the same image set used to create the HSR volume.)
• If you skip incremental images in the image set when you select one to update the HSR volume, Recovery Environment automatically applies all intervening incremental images up to and including the one you selected.

Warning! The Recovery Environment HeadStart Restore requires you to keep the last incremental file used to update the HSR volume if you want to apply future incrementals. If HSR cannot find this last incremental, the HSR volume effectively closes and can then only be finalized. You cannot add further incrementals to it.

The loss of the last incremental that was added to the HSR volume can occur when:

• The user moves the last incremental to a new directory. (HSR expects to find it in the same directory with the rest of the backup chain.)
• The user deletes this last incremental.
• ShadowProtect deletes the last incremental due to the job's retention policy.
• ImageManager deletes this incremental as part of the retention settings for this job's consolidation policy.
• Note: This can occur only when performing an HSR procedure using the Recovery Environment. An HSR procedure run through ImageManager automatically protects the last incremental from deletion because of a retention setting.

To perform a manual HSR procedure, Arcserve recommends temporarily disabling consolidation and/or a retention policy in both ShadowProtect and ImageManager until the user finalizes the HSR volume. This avoids prematurely closing the HSR volume to further updates.

• In ImageManager:
• Click Retention Settings in the navigation pane.
• Uncheck the setting for Automatically clean up backup image files in this managed folder.
• In ShadowProtect:
• Right click on the backup job.
• Select Edit Job.
• Select Advanced.
• Select Keep all images in the Retention pane.

Encrypted Backup Image Files

If the backup image is encrypted, you must specify the appropriate password to access the backup image file to apply it.

Incremental Application Options

The Restore Wizard can apply one or more incrementals to an HSR volume:

• Using the wizard interface
• Using the volume's right-click menu
