MSDP changes in NetBackup 8.1
The NetBackup 7.7.x or 8.0 to 8.1 upgrade includes a rolling Media Server Deduplication Pool (MSDP) data conversion. This conversion works in the background to convert all existing data containers to the AES encryption and the SHA-2 fingerprint algorithm. You can manage and monitor the rolling data conversion with the crcontrol command. More information about the use of the crcontrol command is available. See the rolling data conversion sections in the NetBackup Deduplication Guide. Additionally, refer to the crcontrol command in the NetBackup Commands Reference Guide.
The rolling conversion is performed when the system is not busy. In other words, the conversion runs when backups, restores, CRQP, CRC checks, compaction, etc. are not active. This conversion is not expected to affect normal system operations. After the rolling conversion is finished, there is no difference between the converted system and a new installation.
No explicit steps are required for conversion process during the upgrade of NetBackup. After upgrade, the rolling conversion begins to work in the background. Once the rolling conversion is started, is not possible return to the original NetBackup version. More information about the rolling conversion is available. See the rolling data conversion sections in the NetBackup Deduplication Guide.
