Troubleshooting:Restore backup

From MathLab

Jump to: navigation, search

The files in your home directory are backed up every day in the early morning. These backups are kept for 4 days in order to provide a reasonable time window in which to restore lost files, but not use up too much disk space. To restore the files:

  1. Click on the fedora button.
    • (Typically in the lower left corner of your screen on the taskbar.)
  2. Select "Mathlab" from the pop-up menu.
  3. Then select "File Backup Retrieval" from the sub-menu, and click on it.
    • This will open a file browser, showing the files and folders in your home directory.
  4. Here's the part that's a bit confusing. You first have to double-click on one of the directories before the "Back" button is enabled on the file browser.
  5. Now click the "Back" button in the upper left corner of the file browser.
    • This will take you to the .ckpt directory in your home directory, where the backups are stored. Here you will see 4 folders: one dated today and the others dated the previous 3 days.
  6. Double-click on the folder dated for when the desired file existed, or contained the information you want to restore.
    • This will show the contents of your home directory from that morning.
  7. Find the file you want to restore.
    • If the file was on your desktop, then it will be in the "Desktop" folder, etc...
  8. Once you've found the file, right-click on the icon for the file and select "copy" from the pop-up menu.
  9. Then you can paste it to your desktop...
    • Right-click on your desktop and select "paste" from the pop-up menu.
  10. or paste it to the location of your choosing...
    • Double-click on your home file folder "(userid)'s Home" to open a new file browser.
    • Open the appropriate folder where you want to restore the file to.
    • Right-click in the file browser window and select "paste" from the pop-up menu.

* Note: This will only recover data that has been stored overnight. If it is a file that was not on the system overnight, then unless the file was simply moved to trash which was not emptied, there is no way to retrieve it.

* Note: If it's been more than 4 days since the file had been deleted or changed, the CEC might be able to help. Send an e-mail to In the subject line, put "File Backup Retrieval". In the body of the message, include your userid, the name of the file you want restored, which folder (or series of folders) the file was in, and a date when the file had the desired data. (It would also be helpful if you let the CEC know if you are a math major, non-major, or partner(lab consultant), but it is not necessary.)
