Well, it definitely beats not having a backup at all, right? Well with Synology backup tools, it was clear that the intent behind it all was that there was no need to stress out over losing a file or restoring it. Restoring from a backup is always stressful and people don’t like it. What if we take that same crypto incident but this time if your data gets encrypted you can just go back in time and restore an early version of that same file good as new? Great right? Well, let's see how that works and what you need to make that happen. So, I already scared you enough, and still no word on what snapshot is. Having all your data on your NAS without a proper backup of that same data is just the same as keeping it all on your computer. IT IS NOT! RAID is not a backup, it's just a redundancy solution so you don’t have to stop working if one drive for example dies (and they will).
Most people think that running all your data on a RAID array set up on your NAS is backup. If your data is stored on your NAS and that folder gets encrypted it's game over. Now, if that is your only backup, then you are done, right? The same thing applies to your NAS. The only way to get it back is 1) paying the ransom to get the unlock solution (don’t do this!) or 2) restoring from backup. What will happen is that all your data will be encrypted and if your USB drive that you have your backup on (or your NAS for that matter) is plugged in your computer (or accessible on the network), chances are your data will get encrypted and that will be it. Suppose you are infected with a modern version of a malware, a cryptovirus. Now, what is a snapshot and how is it different from your usual copy backup that you transfer your data on a USB stick or NAS? Well, let's run this through an example. There I talked about an Active Backup for Business package (that also doesn’t mean it's for business use only!) and showed a few methods of how you can use that tool to keep your data safe. Keep in mind that this does not necessarily need to be a business topic because as long as you have a NAS that supports the snapshot package there is no reason not to use it.Īlso, this is another, separate package and scenario, that has nothing to do with my previous article: 3-2-1 > Active Backup. Specifically, I will focus on a more business end of the spectrum and talk about snapshots today. Well know that we know that you don’t (shame on you), lets's see what Synology NAS can do for you in terms of keeping your important data safe. I’m talking about documents, configurations, settings, online passwords, emails, you know, the IMPORTANT stuff. You do have backups right? I mean for everything? Not just your pictures and videos on your phone. UPDATE: added replication recovery process on the bottom Replication recovery methods.
