#GOAL: Creates a backup and removes some of the previous backups
#HOWTO: call it via cron as frequently as you want
#The Nextcloud app is excluded from the backup due to its size. TODO : find how to save calendars and contacts but not the files.


# Backups are created with the following prefix
PREFIX="auto-"
# All backups with the previous prefix are deleted except the following dates
TODAY=`date '+%Y-%m-%d'`
LAST_WEEK=`date -d "7 days ago" '+%Y-%m-%d'`
BEGINNING_OF_MONTH=`date '+%Y-%m-01'`
BEGINNING_OF_LAST_MONTH=`date -d "last month" '+%Y-%m-01'`

#separation between apps and config

yunohost backup create -n $PREFIX$TODAY-core --system
yunohost backup create -n $PREFIX$TODAY-apps --apps `yunohost app list -i | grep id| sed 's/id: //' | sed 's/nextcloud//'`

#Removal of old backups
cd /home/yunohost.backup/archives
rm `ls | grep $PREFIX | grep -v "$TODAY\|$LAST_WEEK\|$BEGINNING_OF_MONTH\|$BEGINNING_OF_LAST_MONTH"`

#last line to check, useless in cron mode
#yunohost backup list
