Data Backup and Recovery Policy

Web and mysql Databases

  • Backed up data stored on ITS's Unix/Linux Network Storage includes but is not limited to: Web space (live, test and staging) and mysql databases.
  • All Unix/Linux Network Storage data is fully backed up weekly on Saturday morning.
  • All Unix/Linux Network Storage data is incrementally backed up Monday through Friday evenings. "Incrementally" means that any file that has been added or changed since the last full backup is backed up.
  • Backup tapes are kept for six weeks. A new set of backup tapes is loaded weekly. One set of tapes is stored off site for three weeks during its six-week cycle.
  • The oldest Unix environment backup data available for restoration is six weeks old.
  • Unix/Linux data is recovered upon request to ITS. Normal turn around for a restore request is one business day.
  • ITS will work with users and departments on creating data archive tapes on a case-by-case basis. These tapes would be separate from the normal tape rotation process and kept for 2 years.

Network Space

Please note that neither your personal home drive nor any shared drives should be used to store personal pictures (.jpeg, .png, bmp, tiff), audio (.avi), or music files. These personal files also greatly increase the costs of our backups and slow down the daily and weekend backup process. To preserve space on the network and to ensure the backup process continues to remain seamless, please delete any non-HLS specific files. We regularly scan our servers for audio, video, and music files. If you have personal files, you may be contacted and asked to remove them from the HLS network.
