Background: I currently have a 3rd party backup appliance that backs up our data (Oracle datapump dumps) and replicates it to another data center. However, my data size is growing larger every week and my replication has fallen considerably behind (approximately 2TB of data every week).
Possible Alternative?: Is rsync (run perhaps once a day or once a week) viable as an alternative solution with, say, Oracle DBF files (all the stuff contained in /u01, /u02, etc)? That way we maintain a single copy remotely that we can basically cp (on the remote server) once a week for weekly backups, but considerably reduce the amount of bandwidth required to transfer an entire copy of the database every week.
Here's a (shitty) diagram just in case that wasn't clear:
"data" [local servers] | rsync "data" (once per day or week) | [remote servers] "data" (weekly cron job to cp "data" -> "timestamp.data") Any backup experts out there wanna chime in? Looking for advice from people working in an enterprise production environment.
