 +===== Data Best Practices =====
 +The file server is backed up to an external hard drive adjacent to the storage node, but as a best practice to prevent against catastrophic loss of data, especially for data that you can not afford to lose, would be to duplicate your data on another host or resource. Lehigh University offers a few options for cloud storage:
 +  * [[https://confluence.cc.lehigh.edu/display/LKB/Google+Drive+-+an+Introduction|Google Drive]] - Available to all Lehigh University Faculty, Staff, and Students
 +  * [[https://lts.lehigh.edu/services/dropbox|Dropbox]] - Lehigh University offers Dropbox accounts that can be used for archival and project related work.
