Recovery enables finding and recovering modified or deleted files and folders from snapshots.
Recovery uses Search functionality, to locate files that are able to be recovered.
By default, the Snapshots Only setting is toggled on as shown below. That means searches in Recovery look for items that have snapshots available, from which to recover.
To begin the process of recovering a file, select it from the search results table by marking the check box beside it, located at the left side of the search results table.
This activates the Operations menu at upper right. Select Recover.
- Step 1: Provide a name for the task, eg Restore DocOne.docx. This name is used as an identifier on the Tasks page, and in Notifications once it's completed.
Specify whether to recover the selected item in its original path or to a different path. If cloning to a different path, enter the new path (including the node). You may also enter email addresses to be notified when the task is completed
- Step 2: Check and confirm your task details and click Next Step to initiate the task.
Specifying the Snapshot to Restore
When snapshots are available for an item in the search results, a snapshot link will be visible in the Snapshots column (the right most column) in the search results table. Clicking this link will display the available snapshots in a popup window. From that window, users can select the snapshot they like, for recovery, and through the same above mentioned three step process.
Users may narrow down search results using filters are accessible through the left hand panel of the Recovery page, as follows:
- Search In: specifies the nodes in which to search. By default, all nodes of all clusters are selected to be included in the search
- Age: specifies the age range of last modification made to the file or folder. The File Age Range has the following three options, and none of them is selected by default
- Hot: less than seven days
- Warm: less than thirty days, but more than seven days
- Cold: more than thirty days
- Date: specifies the dates between which the last modification was made to the file or folder. The Date Range is not set by default
- Type: specify whether to search for files, folders or both. File is the default value for this filter
- Snapshots Only: through which users can direct the search results to only include snapshots. The Snapshots Only filter is set to ON by default, meaning that search results will only include files and folders that have snapshots
- Size: through which users can filter the search results based on the specified size range for the search targets
- Advanced: through which users have access to some of the above mentioned filters all at one place in editable test format. Additionally, in the Advanced Filter, users can specify the Page Size and Wildcard for the search results
The filters that have selectable options, have All and Clear options for selecting and deselecting all the filters’ options, and all filters have Apply options, which apply and run the search for the filtered results.
Recovery: Search Results
For any search conducted through Recovery, the resulting information is presented in a tabular format and includes the following information:
- Number: the number of the found items for the search, including files, directories and snapshots
- Name: the names of the found items, i.e. files or directories names
- File Path: the paths of the found files or directories inside the file system
- DFS Path: the paths inside the Distributed File System, i.e. Target + File Path
- Folder: which indicates whether the found items are directories or not
- Target: which is the node on which the directories that contain the found items are created
- Size: the sizes of the found items
- Last Modified: the timestamp on which the found items are last modified
- Created: the timestamp on which the found items are created
- Snapshots: the available snapshots that contain the found items
- The search results table can be configured to display or hide columns through the Columns button on top of the results table. That includes all of its columns, except for the Name and Snapshot
For any item in the search results, users can access the Actions dropdown menu for Recover and Audit, as follows
- Audit: shows the complete audit history that Data Services has for that item
- Recover: recovers the file to the requested path in the file system
- The search results may be Exported into downloadable files in CSV or Excel file formats for external use. The exports are scheduled tasks and exported files could be downloaded in the Data Service Tasks page
- By default, 100 files per page are displayed, with a "load more" button below the search results. The default number of 100 can be changed using the Advanced filter and "pagesize=" directive.
