We will explore how backup applications work with VSS to produce reliable backups for Windows Servers and Applications. Learn the components of VSS and how to use the command-line tools to investigate the workings of “snapshots and shadow copies”. How is it different from cloud applications using “snapshots” and how to troubleshoot the problems with VSS?

WOW Lowell I think this is your most complex video ever done 😃 VSS and Backup systems in general are really complicated to understand, but when all is running fine it's ok until you have a problem and you realize it's very hard to troubleshoot. I had two types of issues with VSS on servers: - when you run vssadmin list writers and the "system" writer is not listed anymore, you know you will have a hard time troubleshooting. I had this issue on 2 servers and I spent many DAYS trying to solve the issue but at the end I re-installed the server, so I never knew what was the root cause (I hate to do that but sometimes we have no choice). - then some years ago a lot of our files servers became full of used space on C: drive and also on Data drives, I got into VSS to realize it was because of this UNBOUNDED setting by default, a lot of shadow copies were eating all my drives. I set it to 300 MB and deleted the old shadow copies and then I was able to have a lof of space back (on one data disk I even got HUNDREDS of GB back after this cleanup!!!). I will download you notes because I know I will learn new stuff , thanks again for all this amazing work.

Docteurgreene, I was surprised Microsoft's backup set the UNBOUNDED attribute on shadow storage on the backup disk, I would think that would only be used if you dedicated a disk to shadow copy. Of course you can do all this manually but you would hope for better auto configurations. Troubleshooting VSS can be simple "reboot" and very complex. I also had a critical server and could not get backup to complete and after many frustrating days reinstalled. I would have loved to engaged Microsoft tech support but schools just do not have the budget. It was up to the admin to fix it.
