Backup Exec D2D Retention Settings

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?

Okay, so changing the number of days for overwrite protection does not affect the data already present in your D2D folders.

That only works moving forward.

So to delete the past, excess data:

View the various entries in your D2D folder under DEVICES.
Sort by date to see the entries you want to keep as well as the entries you want to delete.
Keep in mind, you have to retain the B2Dxxxxxx and IMGxxxxxx files for each D2D backup you want to keep.
Otherwise, highlight the dates you want to delete and choose ASSOCIATE WITH MEDIA SET
From here, choose the RETIRED MEDIA option from the drop down list.
Now choose to delete.

This effectively removes the data from Backup Exec.

Now delete the data from the location on your server where you store Backup Exec’s D2D directory:

Locate the D2D folder in question.
Sort by date
Retain the IMGxxxxx directories that match the names of the IMGxxxxx files that you did not retire \ delete from Backup Exec
Retain the BKF file that matches the backup sets you are retaining (will have similar dates)
Retain the CFG files
Delete the remaining IMGxxxxx directories.

I answered my own question after getting with Symantec support.
