Backup Exec D2D Retention Settings
Posted on 2011-10-26
I have a question on D2D backups regarding the Backup-To-Disk folder settings under DEVICES and the Media Set settings under MEDIA.
Originally, I had a particular Media Set configured to hold several weeks of data for a job that only runs once a week. This backup is then immediately written to tape.
Due to disk space issues, I now only want to keep a single day’s worth of D2D data. Under MEDIA, the overwrite protection was changed to 1 Day with an append period of 0 hours.
After this job ran, I was expecting to only have 1 Days worth of D2D data on hand. Yet I am still seeing data with dates more than two weeks old within the Backup-To-Disk folder for this job under DEVICES as well as entries from several weeks of backups within the Media set folder for this job under MEDIA.
So it looks like you have to manually delete the old data as it is not auto removed after the retention settings are changed and the backup job is run with these new settings.
Yet I am seeing postings on line that seem to indicate manually deleting D2D data as being a bad idea.
So, how do you get rid of old D2D data after you have decreased your retention settings?
