Your NetBackup policies specify a retention period for a backup image. At the end of this time, the backup image is said to be expired. PureDisk’s data removal policies remove expired data from the content routers. PureDisk data removal policies do not remove any data that is backed up with the PDDO plug-in unless NetBackup expired the data first.
PureDisk includes a system policy for PDDO data removal. This policy is enabled by default, and it is preconfigured to run once a week. You do not have to edit the system policy for PDDO data removal, nor do you have to reconfigure this policy.
If you edit the system policy for PDDO data removal, be careful about scheduling it to run more frequently. For example, you do not want to run this policy once on the hour especially on older versions of PureDisk. For PureDisk versions prior to 22.214.171.124 and NetBackup 5000 series appliances with software versions prior to 1.3, when a PDDO data removal policy runs, PureDisk cannot run PDDO backup jobs. The backup jobs have to wait until the data removal policy finishes for those earlier versions.
The PureDisk data removal policy operates on the following types of data selections:
The system policy for PDDO data removal provides a global policy that affects all the data that is backed up with the PDDO data selection. For example, if you have several NetBackup policies that write data to the PureDisk storage unit, they each may have different retention periods. The PureDisk system policy for data removal, however, affects all PDDO data selections.
