File systems on ENGR home directories (Z drive) and research file servers such as "depot" or "farm" allow users to restore previous versions of files and directories from snapshots taken on the hour. This is very useful when a file may become corrupt, or something is accidentally deleted, as you can quickly restore yourself.

The process is fairly straight forward for Windows users. MacOS can restore using ssh and restoring via command line.

From the Windows operating system, right click the directory or file you wish to restore and select "Properties":

Next select the file or directory you wish to recover and select COPY or RESTORE. You may see several versions in the list depending on how many times there have been changes. When doing a RESTORE, it would be prudent to rename the existing file, or just use COPY to be safe: 


A restore WILL overwrite the version you have, so be careful:


Restoring a directory, especially a shared directory, can be tricky. You may not "own" all the files in the directory. Emailing support and ask us to restore for large directory trees would be best.

Also, when doing copies, be cognizant of your quota. It can be easy to exceed your space limitations restoring copies of things, especially large directories. Again, ask support if you aren't sure if you have the space to do a copy.
