PLEASE NOTE THE FOLLOWING DATA STORAGE POLICIES (revised February 2019, in bold):

The internal hard drive (DATA1) is for short term storage only, in order to allow space for new data. All newly created or modified files on DATA1 are duplicated daily (7 days a week) onto the QNAP external drive, creating a redundant copy for long term storage. Files older than 6 months on DATA1 will be deleted whenever the hard drive reaches 90% capacity. Users who occupy >400 GB of DATA1  will have files older than 4-5 months deleted and will be notified of their status. In any case, removal of files from DATA1 DOES NOT RESULT in any loss of data, because the long term copies (up to 1 TB total) are available on QNAP for at least 3 years. After that, QNAP files may remain for up to 10 years if space allows.

ADDENDUM (EFFECTIVE JANUARY 2019):

- Due to limited space on the QNAP, users are now limited to 1 terabyte (TB) of backup. If users need to exceed that amount, I will transfer their excess data to a Google Team Drive. Data from users no longer associated with CWRU will also be transferred to a Google Team Drive and made available to the primary user and/or the principal investigator (lab) indefinitely.

- Due to the automatic daily data backup system (DATA1 -> QNAP), reorganization of files and folders on DATA1 needs to be limited, to prevent duplicates being created and wasting space on the QNAP. Backups to the QNAP generally end by ~3:30pm every day, so if you wait until the afternoon to move files created in the morning, duplicates will be created. Here are some general guidelines to follow:

  1. DATA1: Names of folders on DATA1 should NOT BE CHANGED once they contain data. Otherwise, duplicates are generated on QNAP. For example, during an imaging session you can create a folder with today's date and dump your images there as soon as you are done acquiring them (and leave them there). Alternatively, create project or experiment folders to accumulate images over many days without creating new folders each time. Regardless, you MUST organize your newly created files immediately after each session before the next backup occurs (~3 pm).
  2. DATA1: Existing data on DATA1 should NOT TO BE MOVED to other folders on DATA1. Otherwise, duplicates are generated on QNAP. If you wish to move your files on DATA1 and avoid creating duplicates, you shoud delete the backup copy on QNAP first. Otherwise, just don't move them.
  3. QNAP: Files and folders on QNAP (withing the Backup folder started December 2014) can be moved or renamed, as long as they no longer exist on DATA1. Note: Deltavision (.dv) files older than 6 months are routinely deleted from DATA1 by the administrator (see above policy), so moving older DV files on QNAP does not cause any problem and there is no need to delete them from DATA1 (they have already been deleted).
