If you need to delete some of the Retain directories, using the rm command can be really slow.  Therefore, to help speed up the deletions, you can use rsync instead.  This is to be used at your own discretion. 

Resolution

Be sure to have backups of your files just in case.
When logged into your Retain Server, first you will need to create a new directory in any location of your choice.

mkdir empty_dir

Next, you will run this command.  empty_dir is the new directory you just created and yourdirectory is the directory you wish to remove:

rsync -a --delete empty_dir/    yourdirectory/

Once this command completes, both the new directory you created and the directory you wish to have deleted will still exist but all content inside them will be gone.  you can then manually remove those directories using the rm command.
