backup

this is a simple backup setup that I use on my home server

conf.d contains files that have file glob lists in them, like .gitignore files. ./run then runs restic for each file in conf.d and backs up the file list under the tag of the file name. if a file with the same name as in conf.d exists in pre.d it gets run before restic, and the same goes for post.d but it's after restic. env contains environment variables for restic, and gets sourced by backup.

by default, only the last two backups are stored, and old ones get deleted. this can be edited in forget.

systemd unit/timer files are included
