 ## Backing up your data
 
-`/mnt/data` is snapshotted daily to `/mnt/backup/data-backup`. In case of inadvertent data loss, users can recover lost files from a previous snapshot, organized by date.
+`/mnt/data` is snapshotted daily to `/mnt/backup/data-backup` and rolling backups are kept for six months.
 
 [`rsync`](https://linux.die.net/man/1/rsync) is also recommended for periodically backing up user files to a local client.
 
 * Copy a user's `$HOME` directory locally to `/home-backup` from a client: `rsync -azH --delete username@hartmanlab.genetics.uab.edu:/home/username/ home-backup/`
 * Copy a shared directory locally to the current directory from a client: `rsync -azh username@hartmanlab.genetics.uab.edu:/mnt/data/scans/20250723_roessler_project .`
