Robocopy (Robust File Copy) does one job extremely well - it copies files. For server 2003 and XP it can be downloaded as part of the Windows Server 2003 Resource Kit Tools. Robocopy ships with Vista, Win7 and Server 2008. Sometime later I was introduced to Robocopy.aspx). This quickly grew out of hand as the number of files increased. Hence I started taking backups of MyShare/A, MyShare/B, etc. Their forums are filled with people asking for solutions, though the only suggestion they have is to split the backup job into several smaller jobs. Apparently it was simply unable to handle more than a million files (give or take a bit). Some time later ViceVersa stopped working. It worked great for some time although it wasn’t the most speedy solution given my scenario.

I started out using ViceVersa PRO with the VVEngine addon for scheduling. Finally I’d only have access to the files through a share so it wouldn’t be possible to deploy a local backup solution that monitored for changes and only sent diffs. All changes would be additions and deletions - that is, no incremental updates. While seemingly simple the only hitch was that there would be several thousands of files in binary format, so compression was out of the question. Recently I needed to implement a very KISS backup solution that simply synchronized two directories once a week for offsite storing of the backup data. I’ve used it for synchronizing work files from my stationary PC to my laptop in the pre-always-on era (today I use SVN for almost all files that needs to be in synch). On numerous occations I’ve had a need for synchronizing directories of files & subdirectories.
