Database backup
A full database backup is quite simple.
$ mysqldump -u [username] -p[password] -h [host] [databaseName] >PVLng-$(date +"Y-m-d").sql
It just dumps all data into a date stamped SQL file.
Backup with API
If you are interested in CSV/TSV data as backup, you can do this by requesting all data for a channel via the API
$ GUID=your_GUID_here $ wget -o PVLng-$GUID-$(date +"Y-m-d").csv http://your.domain.here/api/r3/data/$GUID.csv?start=0&full=1
- start=0 - all data since 1970...
- full=1 - extract also the readable date+time column
