#What is this
This is a docker for a cron job that runs rsync to backup folders.
the backup.sh is the backup script but the cronjob call list.sh which thenc calls backup.sh
this is to make listing multiple folders easier.

#Setup
#Source and destination
On docker compose you'll find volumes
```
    volumes:
      - /path/to/sources/:/source/
      - /path/to/backups/:/backup/
```
change `path/to/source` and `path/to/backups` to the paths where the folders you'll want to backup are and where the backup is going to

##List
```
/usr/local/bin/backup.sh /source/project1 /backup/project1-backup --keep-trash=false --rsync-delete=true
```
this is the list the cronjob will run.
`/usr/local/bin/backup.sh` is just the name of the backup script, does not need change
`/source/project1` Param 1 is the folder you want a backup of, if need change
`/backup/project1-backup` Param 2 is the folder where the backup will go
`--keep-trash=false` Param 3 is if a "trash" folder will be kept, this means that any file deleted from the source folder will have it's latest backup moved to a "trash" folder where it'll stay for 30 days, after that, it too will be deleted 
`--rsync-delete=true` Param 4 if used, delete flag will be called for rsync, deleting any file on backup folder that has been deleted from souce

if both are false, then any deleted files will be kept indefinitely in the backup folder.


#Building and running
build with
`docker build -t cron-backuper .`
and use `docker compose up` to bring it up(it's easier to config volumes that way)
