Search to Find

Enter keywords in the folder or file name you are looking for. To ensure privacy, Backup for Microsoft 365 does not search the content of files.

Note: currently, the Backup for Microsoft 365 UI has a search result limit of 500 items. To narrow the search, you can browse to search within specific folders or sub-folders.

Search to Find

Backup for Microsoft 365 also supports a variety of Advanced Search capabilities, including Elasticsearch, Wildcards, and RegEx.

Note: for a RegEx search, enter "RegEx:" before the query.

If multiple items appear in your search, you can sort the items by date modified, file type, and size.

Browse to Find

Click any folder or sub-folder to browse its contents. You can then sort the items in a folder by date modified, file type, and size, or filter them by date.

  • Sort: To sort, click the column heading you want to search by
  • Filter: To filter by date, click the filter icon and select an option

As you drill into folders, your path is tracked at the top of the screen. If you want to navigate back, simply click on the path to open a menu, and select the folder you want to return to.

Individual Item Restore

To restore individual files or folders, select them and click Restore.

Note: when needing to restore more than 200 individual items, it is best practice to perform a bulk restore (e.g. full mailbox, folder, list, etc.) or perform multiple batches of under 200 individual restores. Currently, extremely large batches of individual restores (e.g. over 200) may not complete.

Individual Item Restore

Note: you can restore multiple items, including different item types (e.g. files and folders) with a single click.

Important: every OneDrive for Business restoration is a “new item” restore because Backup For Microsoft 365 does not overwrite existing items. This means that if the item being restored already exists, Backup For Microsoft 365 will add the restored item back to the site collection with its name appended with a number in parentheses. On the other hand, if the item does no longer exists, Backup For Microsoft 365 will add the item without appending the name of the file.

Full Account Restore

Backup For Microsoft 365 also supports the restoration of an entire OneDrive for Business account. On the homepage of the OneDrive for Business tab, click the ellipsis (...) in the Actions column of any User, and click Restore Full Account.

Full Account Resotre

This will open a window with more information about this action. Click Confirm if you want to proceed.

One Drive for Business Restore

Important: when a full restore is done with Backup For Microsoft 365, it is merged with existing content. In other words, the data is de-duplicated before it is inserted into the account. Backup For Microsoft 365 does not overwrite or delete data at any time.

Previous Version Restore

By default, Backup For Microsoft 365 will restore the most recent version of a file. However, if versioning is enabled you can restore previous versions. To do so, click the ellipsis (...) under Actions, and click Version History to open a window in which you can select the version you want to restore.

Previous Version Restore

Restore Process

While the restore is initiated with a single click and Backup For Microsoft 365 makes every effort to restore the content as quickly as possible, the time required to complete the restoration is based on a variety of external factors, including:

  • The overall size of the data set being restored.
  • Microsoft Office 365 throttling.
  • Microsoft Azure throttling.
  • The overall availability of Office 365.

During this time, you can view the status of the restore by hovering over the progress indicator next to the mailbox being restored.
