Recovering UVM Silk and Zoo Files and Folders on MacOS

Macintosh OSX:

Recovering Silk and/or Zoo files on a MacOS machine.

This guide offers instructions for how to recover lost files or folders for UVM’s Silk and Zoo servers.  You will only be able to recover files and folders that have been backed up by the server between 3 months prior to the recovery attempt, and 24 hours before the recovery attempt.

This means that files and folders created and deleted in the same day are not recoverable. Additionally, any changes that have not been backed up by the server will not be recoverable.


Connected To Your Server Storage using SSH in Terminal

  1. In Finder, click the “Go” menu and select “Utilities
  2. From the Utilities menu, scroll down and double-click on the “Terminal” icon.
  3. A Terminal window will appear. You will need to login using your UVM NetID and password. You will also need to specify which server you wish to access at this point.
    1. To log into your UVM Zoo space, type: ssh then press Enter
    2. To log into your UVM Silk space, type: ssh then press Enter
      If you are not sure which service you should be accessing, please contact the UVM Tech Team.
  4. You will now be asked to enter your UVM password. Enter your password, then press Enter.
    *NOTE*: The cursor will not move as you enter your password. This is normal.
  5. You should now have successfully logged into Zoo or Silk!


Recovering Your Lost Files

Now that you have successfully connected to your Server Storage with SSH, you can begin the recovery process.

  1. In the Terminal window, type in the “recover” command, then press Enter,
  2. Using the “changetime” command, you can access a backup from a time before your file or folder was deleted.
    1. Change the time to yesterday by entering “changetime yesterday
    2. Change the time to last week by entering “changetime last week
    3. Change the time to a specific date by entering “changetime mm/dd/yy

      *Note*: Backups occur nightly. As such, you will only be able to recover files and folders that were on your server storage when the last backup was run. Backups are stored for up to 3 months.
  3. You will now need to navigate through the backup and select which files and folders you wish to recover.
    1. To view a list of these files and folders, use the “ls” command (LS), then press Enter.
    2. If you are trying to recover a file or folder within another folder, use the “cd <Folder>” (replacing Folder with the name of the folder) to get into that folder, then press Enter.
    3. Select a File to add by entering “add <FileName>” (replacing FileName with the name of your file) then press Enter.
    4. Select a Folder to add by entering “add <FolderName>” (replacing FolderName with the name of your folder), then press Enter.

      *NOTE*: You need to enter file and folder names exactly as they appears. You also must use quotations around file and folder names that include _spaces_ and/or Caps.
  4. Now that you have marked files and folders for recovery, you can start the recovery process by entering the “recover” command, and pressing Enter.

  5. To complete the recovery process, enter “exit“, then press enter. The files and folders are not actually moved until after you type the “exit” command. 

That’s it, you’re done!
