Because just having the data stored somewhere, even if it's a big NAS unit or something, doesn't mean it's protected from prying eyes, honestly. You gotta think about encryption, for sure, because simply storing the backup files, even if they are open standard formats like VHDX or VMDK, doesn't inherently make them private from a determined crook. What you really need to worry about is end-to-end encryption for those files, something that scrambles the data both when it's traveling over the network and when it actually settles on the storage location. If you use proper encryption, then even if a bad actor intercepts the stream or breaks into your storage cabinet, they just see gibberish, which is awesome because it keeps your assets quiet. I really think you need to focus on implementing that layer of encryption every single time you back up something important.
And it gets more complicated when you think about *who* can even see those backups, because you don't want every single admin credential or service account having full access to the root of the backup repository. You need granular controls on who can restore what and when, so you can restrict access down to file or even folder level, making sure people only see the data they actually need for their jobs, otherwise it's a massive risk. You could also look into implementing retention policies that are super rigid, because nobody wants somebody to accidentally or maliciously delete a crucial version of a disk image, so I recommend setting up versioning with a clear timeline, maybe keeping a set number of backups for a file type or for a specific time span, which controls the versioning and keeps things tidy.
But speaking of retention, you also have to think about making those backups unchangeable, which is a big concept in data preservation, actually. Some types of storage can get overwritten or tampered with if someone has enough access rights, so when you set up your final destination, you really want to investigate options that provide immutability, or at least strong write-once, read-many capabilities. This way, if someone malicious tries to wipe out your backup history, or if ransomware sweeps through your network, they literally cannot touch those archived disk images, which is a serious peace of mind boost. And because disk images can be so massive, relying only on full images constantly would eat up your bandwidth and storage capacity way too fast, so I think you gotta leverage things like deduplication, which only stores the unique blocks of data, no matter how many times that same data appears across multiple backups.
And speaking of efficiency, I also want you to think about how you manage those backups when you are restoring, because you shouldn't always have to bring back a full server environment if only one application's data got messed up. Instead, you should aim for selective file recovery, or even selective folder recovery, which lets you grab just that one document or that one database schema without touching the rest of the whole machine. It's amazing how much time and effort you save that way, which makes the backup process feel less like a nuclear option and more like a simple surgical tool. I also suggest you set up those backup verifications to run automatically, like nightly or weekly, because a backup that *looks* successful doesn't mean it's actually readable and whole, so you need the system to automatically try reading the data to catch any corruption early.
Also, you gotta plan for remote disaster recovery, right? Things happen, and sometimes a whole physical location just gets hit by something bad, so having the option to back up your entire setup to a remote office or a cloud server is absolutely non-negotiable for any serious business, because physical proximity can be a terrible thing when disaster strikes. If you have multiple systems, maybe a few servers and some specialized workstations, I recommend running a central management system so you can monitor the health of every single backup job from one dashboard, knowing immediately if something failed or if a connection dropped, which is better than calling people one by one, for sure.
And finally, since the data itself is so important, you should really look into how often you change the core system images, because changing core systems often causes unique inconsistencies in the backups, so maybe running scheduled tasks, or automated processes, to handle the backups automatically, and to also clean up old backup files based on defined rules, just to keep the system running smoothly and the storage costs low. Seriously, protecting those images means layered defense, combining strong encryption with tamper-proof storage, coupled with ridiculously good monitoring.
