Zip, nada. I use Keepass.

NovaBackup for file backups (dev source, etc). Use an external drive and keep 7 days' backups. Cobian backup for VMs. I can't say enough good about Cobian: it's free and uses ZIP format for the archives, so any unZIPPER can restore files. It has a very decent user interface, can be scheduled or run manually, and can run scripts either before or after a job. And, an entire backup job or set of jobs can be scripted. Again, I run a 7-day backup cycle to an external hard drive. For SQL server, I use the native SQL backup engine and run scheduled SQL backup jobs. The backup files can then be archived with any backup tool, including OneDrive or Dropbox.

Robocopy running from a scheduled batch file (as mentioned by others) is a good choice. Also, take a look at Cobian backup. I've been using it for years. It has a built in scheduler so can run unattended. The only possible downside is the backups are stored in ZIP file format so an unzipping application is needed to access the backups. 7ZIP is a freebie that could accomplish that.

Another thumbs up for VisualSVN plus the Tortoise SVN client. Very intuitive. If you have access to a remote server you get the additional security of off-site repository storage.

I use RDP and Logmein. Both are free but Logmein is very easy to set up and works via a browser interface.
