Restoring Information From Your Backed-up Institutional File Server Folder

Files that you store in your Home or group folder on U-M's Institutional File Server (IFS) are automatically backed up. This document describes how to access the backups of your files should you need to.

FOLDER VERSUS DIRECTORY: These two terms are used interchangeably. Directory is the older, more technical term for a folder. In this document, folder is used.

Retrieval Methods

For your convenience and the security of your data, Information and Technology Services (ITS) regularly backs up your files stored in the Institutional File System (IFS).

If you mistakenly delete or change a file stored in IFS, there are two ways for you to recover it from your backed-up files:

• Access the most recent backup of your home or group folder by yourself anytime at no cost.

• Request a restore from any of the preceding 14 days or for a weekly backup from the past eight weeks.
  TIME AND COST:Your entire Home or group folder will be restored as soon as possible although the recovery may take up to one business day. This service typically has no cost; however, ITS reserves the right to implement a charge for requests that will exceed the time and resources expended for a standard restore. You will be advised of any cost prior to performing the restore. For students, the fee will appear in their student account. Faculty and staff members should provide a departmental account or shortcode.

Accessing Your Most Recent Backup

A new backup of your files is typically created once per day. This is usually done in the early evening. That backup is always available to you online, and you can do immediate restores from it at any time. Use any of the following methods, presented in order of ease and convenience:
