13 File-Level Recovery
NEWS supports file-level recovery. N2WS performs a backup on the volume and instance level and specializes in the instant recovery of volumes and complete instances. However, in many cases, a user may want to access specific files and folders rather than recovering an entire volume.
N2WS also provides the ability to locate the same item across a chain of consecutive snapshots during a single recovery session.
In previous versions of N2WS, you could recover a volume, attach it to an instance, mount it, and then access the data from within that instance. After completing the restore, assuming the volume is no longer needed, the user needed to unmount, detach and delete the volume. N2WS now automates this entire process.
In the Backup Monitor, select an instance or volume backup and then select
Recover. In the Recover screen, select
Explore in the Instances or Independent Volumes tab. When selecting
Recover Volumes Only,
Explore is available in the Volume Recovery screen.
If there is more than 1 backup available to view, the File Level Recovery dialog opens showing the number of backups.
- 1.To view an instance across a chain of snapshots, select the number of available backups to view.
- 2.To view the latest backup only, leave the value at the default of 1.
- 3.Select Start Session.
N2WS will open the Initializing File Level Recovery message.
Select Open Session for an Explorer-like view of the entire instance or a specific volume, folder, or files. Loading the session may take a few seconds. If the Initializing File Level Recovery message closes before you can select Open Session, in the left pane, select the File Level Recovery Sessions tab, select the active session, and then select
You will be able to browse, search for files, and download files and folders. Use the left and right arrows in the left corner to move between folders.
Select any file or folder and then select
Download. Folders are downloaded as uncompressed zip files.
To perform these operations, N2WS needs to be able to use AWS credentials belonging to the N2WS server instance account, with sufficient permissions to create and attach volumes. By default, N2WS will use the same credentials used to initially configure the instance, but they can be modified using the General Settings screen.
File-level recovery requires N2WS to recover volumes in the background and attach them to a ‘worker’ launched for the operation. The worker will be launched in the same account and region as the snapshots being explored, using a pre-defined worker configuration. See section 22 to configure a ‘worker’ instance in the region that the snapshots exist.
After you complete the recovery operation, select Close for all the resources to be cleaned up and to save costs. Even if you just close the tab, N2WS will detect the redundant resources and clean them up, but it is recommended that you use Close. Sessions can be closed from the File Level Recovery Sessions tab also.
