The backup policy on the home and project space is nightly backups which are retained for 30 days, while deleted files are retained for a further 60 days - note that is entirely distinct from the age limit for purging files from the scratch space. If you wish to recover a previous version of a file or directory, you should contact [[technical support]] with the full path for the file(s) and desired version (by date). | |||
