+# simple-backup
+This creates a backup on the local filesystem, but does not persist it anywhere else. Right now
+the best solution i have to to manually upload this to proton drive.
+
+## configure
+Can add new backups to this by adding another conf file. See services.json for examples and exclude patterns for more details.
+
+## running
+Can run with ./backup.py, or create a cron job.
+current crontab entry is. (every sat at 0105.)
+```
+sudo crontab -e
+5 1 * * 6 /home/craig/services/simple-backup/backup.py >> /var/log/simple-backup.log 2>&1
+```
+want to change this to once a week or something, just like on sunday
+## exlude patterns
+Uses simple "filter" in "path", so no globbing/regexing.
+
+For directories, having a trailing slash means it includes the dir but none of its contents.
