Re: [Veritas-bu] How to use the DataDomain system cleaning process

Hi All,

I have both DD admin guide and Netbackup-DD best practice guide. I am not sure if the attachment size of 6 MB is acceptable as my previous mail with attachment is under moderator's approval.

Thanks ,

Data Domain appliances run a cleaning cycle on a schedule set by the system administrators. In our environment (2xDD560's and 2xDD430's) we run a clean every Monday at 8am which takes about 2 hours to complete. You can run a clean as often as you want. The cleaning cycle takes its cues from whatever backup software you use (in our case Netbackup). If netbackup says that a backup image can be expired the Data Domain appliance marks those blocks as allowed to be overwritten next time data is written to the device. All data expiration on the Data Domain appliances uses the retention policies setup in whatever wrote the data to the appliance. I can't find a way to look at the admin guides without having a Data Domain support login. Sorry.
