TL note: “keikaku” means “plan”
Then you find out the back up doesn’t work.
Happened to me last weekend. I made a backup because I was going to wipe out linux temporarily. I decided to backup with timeshift instead of my typical
rsync -aAXHbecause having a GUI was nice. Timeshift refused to restore the backup. It first complained about my subvolume layout, when I made it happy it restored all my files then promptly deleted them. Fortunately backup is just rsync so I restored with rsync.
Meh… If /home is on a separated partition that’s no biggie. Reinstalling Linux, even Arch, takes half an hour at most.
Being with Arch for like seven years or so, it’s only recently I’ve learned one neat trick, upon reinstalling the system I have on various Windows tablets. I start sshd, do passwd and connect from my main machine. Then I just quickly format disks, and pacstrap system by copy-pasting commands from my blog, where I have the instructions for my devices. It’s not the very techy way, I guess, but I was able to reinstall my system within like 10 minutes, most of which was booting off the USB drive with Arch ISO, and then downloading the packages and waiting for them to be installed, and rebuilding Initramfs.
How?
Ever heard of btrfs? It likes to kill itself
How do you know it was btrfs, are you living in my walls?!
Well, jokes aside, it was a power outage. In my defense, I’ve survived dozens of power outages while using btrfs with almost no negative consequences!
I wonder if the stability pros of btrfs outweigh the instability cons of btrfs; yes, snapshots might be nice, but if the filesystem gets easily corrupted, what kind of trade is that then? Call me wrong, I have no substantial opinions or expertise on filesystem stability.
Snapshots are surprisingly useful and it’s kinda awesome that it immediately detects corruption, but it’s so fragile because it doesn’t really tolerate any corruption at all and is not very good at repairing it either.
I feel like btrfs is kinda like zfs but without the integrity and backup benefits.
