I wanted to use rsync i.e. delta copy with my QNAP nas at home or to an online backup provider.
What would be the best method to back up an image of the windows server and also sql database and exchange seperetate. also the PST files on each desktop using rsync. is Rsync the best for what it does i.e. backups only what is change at byte level , please kindly advise.
is there a cheap solution online where I can just install and agent on each machine and it will backup everything to the cloud ready for me to retrieve and do bare metal install to dissimalar computers in case the whole building blows up?
