Hi
If you really mean "reboot" then that's fine.
If you mean reformat/reinstall Windows, that's different...
All the real data is on the PC - you can't re-create it by doing a HotSync.
If you are using our Internet Backup system you don't need to - I will send your live data back to you.
If you aren't - don't forget to do regular backups to a USB or external drive.
