Best way to backup root?
I am wondering what is the best or a good way to backup the root partition to another readynas backup volume, so that in the event of volume loss, I can restore my working root partition after having...
On the subject of the OS partition backup, I've done that periodically. But how would I restore i? I'm guessing it would have to be done from support mode so none of the overwritten files are in use.
Thanks for bringing this up and it makes me realize this may not be a good approach for backing up a hypothetically "restorable" root partition. maybe?
you both mentioned a lot of complications I wouldn't know the first thing about how to make sure I hypothetically restored it correctly, which would have to include restoring that /apps mount point and who know what else that Netgear had in there along those lines. And sym links too.
I have detailed notes for how to re-setup my readynas to the state its in now, should I have to do that, which probably takes a few hours, it wouldn't be the end of the world, but yes, it also does rely on the netgear repo still being up in order to do it.
My understand is that libc library is the main thing that build-essential depends, which is what comes from netgear repo. As I recall, there is nothing else in the netgear repo that isn't already up to date in the actual OS that is installed. For some reason they chose not to include libc or up to date version of libc in the actual OS that is installed, so in order to install build-essential, you'd need access to netgear repo. There may be other libs or dependencies that I'm not aware of.
StephenB Enlighten me, if I create an apt-mirror, that is just something located somewhere in my data volume? Approx how big do you think it would be for just one version 6.10.9? Does a Daemon of any kind have to be running of any kind? In the future if I needed to restore build-essential after having manually setup the readynas with all my notes, how could I go about accessing that apt-mirror in order to provide dependencies and install build-essential?

I also checked dpkg.log, and didn't see anything else there either.
