Network backup

Is remote backup something that is even an option in Linux? it probably is, but I have to ask.
And I'm not talking about just a file level backup, I'm talking system level or block level.Oh and I'm referring to a free tool - I know Unitrends can do this (is there an agent involved for Linux?)
What do you mean by remote backups? You just take a snapshot and send it wherever you want. Is that what you mean? If so, every one else's ability to do this is pretty much based on Linux from long ago.

If I understand what you are asking... you just take a normal system image on Linux. And use Rsync or whatever tool you want to place it remotely.
Unitrends cannot do this for Linux, only VMware, HyperV and XenServer guests. StorageCraft can do this with an agent. But it is a normal feature of Linux.

LVM Snaps, RSnapShot, ZFS... lots of options on Linux.

My question is more about how to you backup a bare metal Linux install while not using a SSH/NFS mount point.

Is that really your question? That sounds like a proximate question. What is the goal question?
My guess is you want to decouple storage and wondering how to do that.

Yes decoupled storage.

No system, including Windows, Unitrends, etc. can do this from the system. Pushing backups out whether from the OS or from an agent means that the source system controls access to the resulting storage. It is only a remote system, like the Unitrends server, that can take the resulting storage and make it inaccessible to the clients that allows decoupling. You must have remote logic and control to decouple. It's impossible for Windows, Linux, Mac, etc. to have decoupled storage directly because their ability to control the storage that they use is what makes it coupled.
-
Right, I was assuming exactly that. So, is there an open source/free solution that allows this for Linux?
On the Windows side we have the free version of Unitrends and Veeam for VMs, but I'm not sure of one for bare metal.

You can do it with just a script. It just requires doing the work from a remote machine and decoupling the accounts and access.

Those can become coupled if you share accounts. So it is not a panacea.
