CA ARCserve® D2D r16 Update 2 Release Notes

1.0 Description

1.0 Description

Update includes several modifications and enhancements to improve the quality and performance of CA ARCserve D2D r16.0:

Issues Fixed:

This update fixes a problem with backup jobs failing if a previous backup attempt was cancelled at the beginning of the job. This problem was caused by CA ARCserve D2D trying to remove the previous incomplete backup session at the same time that the next backup job is trying to launch.

This update fixes a problem with the BMR process ending unexpectedly if some files from a backup session data are locked by another process. This problem was caused by another issue when log messages are printed and has now been fixed.

Enhancements:

CA ARCserve D2D has been enhanced to better integrate with CA ARCserve RHA.

If merge/purge operation stops in the middle for any reason, this enhancement now lets you recover files from sessions which are visible on the CA ARCserve D2D UI. As a result, you can also perform BMR from sessions which are visible on the BMR UI without continuing the merge/purge operation and helps you save recovery time.

When file level recovery/BMR is being performed, if some of the files are occupied/locked by another process (for example a CA ARCserve RHA replication), this enhancement now causes the job to fail and an error message will be logged into the Activity Log to inform you that certain files are not accessible.

Known Issues:

The following issues related to CA ARCserve D2D are known to exist in this update:

If the merge/purge process fails, then the Full backup size displayed on the "Protection Summary" portion of the homepage will be incorrect. This problem will be rectified automatically when the next successful merge/purge operation is completed.

Design Limitations:

The following design limitations related to scenarios that involve the CA ARCserve D2D integration with CA ARCserve RHA are known to exist in this update:

If the CA ARCserve D2D backup destination is configured to a NAS share, then CA ARCserve RHA integration is not supported.

Changing of CA ARCserve D2D backup destination is not supported for RHA integration.

For a host-based VM backup destination, you must configure a replication scenario for each VM backup destination.

If the replication scenario is stopped and if merge/purge happens on the host-based backup destination, then the full sync will occur after the scenario restarts.

During the merge/purge process, if you attempt to submit a restore of files or a BMR from the same session where merge/purge is being performed, then the restore/BMR operation will fail. Corresponding error message will be shown in the activity log.

If multiple CA ARCserve D2D servers are using the same network share as their backup destination, then you must configure a separate scenario for each CA ARCserve D2D server.

When CA ARCserve RHA initiates a synchronization or resynchronization process between the master and replica, the data on the replica is not guaranteed to be in a consistent state. Therefore, any CA ARCserve D2D backup cannot be restored from the replica until any synchronization or resynchronization has successfully completed.
