It has happened to all of us at some time or another. You save and close that big document that you have been working on, locking in the modifications that you just made and overwriting the original. The problem is the next day you don’t like the changes. You need the original document, but now it’s gone. This has happened to me more often than I would like to admit.
Normally you are out of luck and need to reconstruct the earlier version step-by-step.
Fortunately you have a No Panic Computing notebook. Your files are automatically backed up in redundant, secure, off-site data centers run by Iron Mountain. The backup even has an automatic versioning system allowing you to restore older copies of the same document. All backed up versions of files are kept for 90 days for you, even if you delete or overwrite them.
File recovery is easy
Here’s how to recover the older version of that file from the Iron Mountain data center.
That's it! The file will re-appear in its original folder on your computer. The day is saved again!
