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...
Does this mirror.list include everything necessary to install build-essential? I'm going to re-do my local mirror and want to be sure to get everything before I retire the NAS with my old mirror. And is it really necessary to have all sub-versions of 6.10.x? I figure all I'll need is 6.10.9 and 6.10.10.
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.
And0when you make your copy, make sure you copy symbolic links themselves, not the content (cp -P), and then separately copy what's linked that's not in the OS partition (/apps is all I know you need).
Has anyone tested how an rsync backup handles symlinks? I know rsync has options for that, but Netgear gave us no options to specify.
And is it really necessary to have all sub-versions of 6.10.x
No. I grabbed them just in case one of the Netgear repos was incomplete.
Not certain here, but it is possible that 6.2.5, 6.3.5, and 6.5.2 installs access the Netgear repo post-install. If so, then folks getting really old arm platforms might need some other versions archived in order to get to current firmware.

Yes, that makes sense.
But you do need to remount as /mnt and copy that, as mount points are not symbolic links. And /apps is a mount point (not a symbolic link).
FWIW, it does make sense to have another copy of the apps folder as part of the overall OS backup, since the restore might be needed after a full factory default.

I haven't. My guess is that you are thinking about a NAS->NAS backup that includes the backed up OS?
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.
Probably best done from tech support mode (and remounting as /mnt and then restoring to /mnt). If you know what you've modifed, then you should probably be selective on the restore.
Personally I have archived my mods, so I'd just restore those. The only app I need is SMB plus, which is also in the Netgear repo. (FWIW, all the netgear-hosted apps are in also in the repo).
Does this mirror.list include everything necessary to install build-essential?
I didn't test this, but it should.
Build-essential itself is a debian package (not Netgear's). It is in both archive.kernel.org/debian-archive and archive.kernel.org/debian. (the version in both is 11.7).
While it didn't install when the Netgear repo was down, it did get the needed libraries when those repo was up. And the mirror includes the full repo.
