# in cron entry, probably in
|
|
# Documentation:
|
|
# In 2022-12, I moved the directories database/ and storage/ that Photoprism uses back to vm4 local filesystems. To back up the app, I just need to run this script with cron.
|
|
# This process should only just over 1 minute
|
|
# Dependencies:
|
|
# photoprism user is in group docker.
|
|
# docker-compose
