I run various openSUSE systems with btrfs file systems. On these setups, openSUSE uses Snapper to manage filesystem snapshots. Every time I finish updating the system using Zypper or the YaST software management tool, htop and iotop show that the Snapper process is busy doing its thing (presumably creating a new snapshot). This activity can last for several minutes.
Sometimes after updating, it's necessary to reboot the system (for example, to load a new kernel). When such a reboot is necessary, is it better to wait for Snapper to finish? That is, are there any downsides to not waiting? Will this prevent Snapper from creating a snapshot, or will it pick up from where it left off once I reboot?
