Are you ready? Let's read!
What is a snapshot?
The snapshot saves the disk at a certain point. All modern storage systems have this useful feature. As a result, the system remains in the state of this moment in time. This saves all blocks that change after this moment.
Using snapshots, you can take advantage of the organization of data arrays. Most arrays create directories to match the actual location of the data. A snapshot takes a copy of the directory and then sets up all the data that it displays as read-only. The storage system creates new entries in the directory and also stores the old directories, which gives a representation of snapshots at a point in time. Although there may be a large number of images, performance will not suffer.
Even if the old catalog is corrupted, snapshots can be perfectly restored, which is another positive aspect of this technology.
How to restore the volume from the snapshot
You can restore a volume using a snapshot in one step: the Restore option.
However, there are a few important things to understand:
- Before you start volume recovery, close the host access.
- Do not expect the recovery to be quick; you need to be patient.
- Also, do not expect excellent performance during recovery.
- If you have data that was changed after the snapshot was created, it will not be restored.
Can you take a snapshot of RAID?
Unfortunately, you cannot take a RAID snapshot because it is not a virtual structure. However, if you are the owner of an array of any level, then you can create a disk image (for example, by using DiskInternals RAID Recovery) and also be protected in case of data loss.
Safeguard RAID data with RAID Recovery
RAID repair utility is designed to recover software and hardware RAID. It is compatible with MegaRAID, Adaptec, HP, Dell, silicone RAID controllers, and DDF devices. Several file systems such as APFS (reader), HFS (HFS Plus), and ZFS with RAIDZ are also supported. Recovery of any kind of data is possible both in automatic (using the Recovery Wizard) and in manual mode (if you have sufficient skills).
Any virtual disks can be mounted as local disks available for Windows Explorer and other similar programs. A free preview of files before restoration will help you to decide whether to purchase a license in order to export data to the drive of your choice and receive free technical support throughout the year.
Here’s what you need to do:
Download and install the application on your PC.
Next, open the application and the Wizard will start automatically.
Each array disk should be connected to the computer.
Using Uneraser or Reader mode. Open the disk from the Hard Drives tab.
All fundamental parameters will be determined automatically.
After scanning, scan the data for free.
The last step is to purchase a license and obtain a unique license key to complete the export of information.
