[GENERAL] scheduled backup

[Apu Islam]

I need suggestion to backup my postgresql server. The database is growing 1/2 Gb a day and I am looking for a solution that would push the data off to the backup server periodically with minimal amount of load to the server (I am trying to avoid table locking). I am thinking to use rsync to sync the data directories periodically. will that allow me to retrieve the data in case of a disaster ? what is the best practise ?
