Table 23 NDMP Accelerator known problems
ID Description
N/A NDMP backup performance for large NetApp volumes
Performance of NDMP NetApp backups of volumes with more than approximately 10
million files may degrade over time. This is typically seen in backups that exceed 24
hours. Both initial backups and incremental backups are impacted.
23067 International character display issue in Avamar Administrator
Some international characters might not display properly when browsing backups in
Avamar Administrator. However, the ability to restore these files is not affected.
29455 Number of bytes reported by Avamar for folder sizes
Avamar 5.0 and later reports incorrect folder sizes in Avamar Administrator. Folder
sizes are routinely shown to be much smaller than the aggregate size of the folder
contents. This does not affect actual backup and restore behavior or data integrity.
35153 Redirected restore of multiple volumes does not work
Redirected restore of multiple volumes fails and results in the following error:
avndmp Error <11803>: [avndmp_assist] Unable to redirect multiple
volumes. Please restore them separately
To work around this issue, restore each volume separately.
48059 If NDMP push upgrade is started while a backup or restore session is active, the
session will fail
If a backup or restore is in session and an NDMP push upgrade is started on an
accelerator, the backup or restore will fail with a dropped session status.
50433 Push upgrades do not work after rebooting an RHEL-based NDMP Accelerator
After rebooting a RHEL-based NDMP Accelerator, push upgrades do not work until the
Accelerator has been re-registered with the Avamar server.
51005 Web download description for NDMP Accelerator does not include Isilon
Web download description for NDMP Accelerator reads "NDMP Accelerator for EMC
Celerra/VNX and NetApp Filers,” and should include Isilon in this description.

ID Description
42770 Display issue for SAP restore with Avamar server release earlier than 7.0
If you restore a SAP plug-in backup with an Avamar server release earlier than 7.0, then
the Activity Monitor displays the restore as an on-demand backup. On-Demand
Backup appears in the Type column in the Activity Monitor instead of Restore.

When backing up SAP with Oracle databases to Data Domain systems, the Oracle
Optimized Deduplication option is not supported.
