[arch-general] back up /var/log before shutdown

Dear all, My /, /boot and /usr are on a BTRFS /(except /boot on ext2) on a ssd. I want to add this line in my fstab to avoid too many writings on my ssd : *tmpfs /var/log tmpfs nodev,nosuid,noexec 0 0* So each time I reboot, my /var/log will be emptied, which could be a problem in case of serious issue on my box. I was then thinking of a way to backup this folder before I shutdown. I found this trick in the Arch forum: add this in my */etc/rc.local.shutdown*: |*echo "Copying LOGs..." now=`date +"%Y%m%d_%Hh%M"` mkdir -p /logs_backup/$now cp -Rp /var/log/* ~/backup/logs_backup/$now/* My ~ folder is on another HD. Will this script be enough to do the job? TY for advising. |
