With an agent-based backup you will need to reboot a system after an install because the snapshot driver resides at the operating system kernel level and hence requires the OS to be restarted.Īgent-less backups actually use a technique called Dispatch Table Hooking which injects code into a running Windows OS system without requiring a reboot. This would seem like a big plus in my mind. Some people prefer the convenience agent-less backups offer because you don't have to restart an operating system (aka production server) when setting up a backup. There are strong feelings in both camps on what the best backup solution is, so I'm going to make an effort to provide you with information so you can decide for yourself.įirst, let me offer my opinion. I'll hang around for a few more minutes to offer a quick reply because I think this is an interesting topic. You caught me just as I was heading out the door. And even if we don't always agree I'm still grateful for the intelligent conversations and thoughtful people I've met since I've joined this forum. If there is a request for technical information and I can help then I'll join the conversation. You'll see from my posts that I'm a normal person who has a great job helping other technical computer people. No, I don't get paid 6 times more than Macrium employees. What this means to you is that if you have critical systems/data and you want reliable backups and guaranteed support then your choice should be clear. This ensures application stability and a quality snapshot backup as the vss writers correctly settle transactions before the snapshot and resume afterwards. running the backup as an agent loaded in the OS at runtime). I can tell you that StorageCraft is a Microsoft Gold Application Developer and that we follow Microsoft's established practices for VSS snapshots (e.g. Finally, I'm curious about how the backup actually occurs which would have a bearing on the overall integrity of the backup. I also understand that Macrium Reflect does not provide customer support for their free product (again off their website). This implies an agent-less backup (the snapshot code is inserted into the stack at the time the backup starts) rather than an agent-based backup. I've also heard that Macrium doesn't run anything on the target system until a backup occurs. They offer a number of similar features to StorageCraft ShadowProtect, for example:Īll of these are straight off of the Macrium Reflect feature comparison.
Ok, all joking aside I'm looking into the Macrium Reflect product.
