Can I backup & restore without KVM?
I'm Linux newbie who just started using dedicated server.
In VPS, backup, restore, and OS installation was just one-click thanks to SolusVM.
However, it seems like everything takes money in dedicated server.
Here is my brief server configuration :
SSD 16G (System) & HDD 1TB (backup & personal data)
Now, I want to install my OS in SSD and back up file system into HDD.
It seems like "dd if=/dev/hda of=/data/disk1.img" will make my backup easy.
However, I think it should be a bad idea to overwrite system disk directly with commands like "dd if=/data/disk1.img of=/dev/hda" while Linux is working on it.
The guideline I found on web tells me to boot as CD and overwrite system disk with dd.
However, I don't want to spend extra money to buy KVM.
Is there any method I can backup & restore from remote with SSH & remote reboot feature?
