I've a linux VPS hosted in a VPS datacenter.
I need to implement backup on it. I'll order The Planet's Stored Cloud to do this. http://www.theplanet.com/cloud-storage/
My question is about the Backup Strategy:
Today I have other servers and I use a rsync backup by week. I get a full backup at the beginning of week, and increment this along the week.
In the backup server I've something like it:
By week, I'm using rsync --delete. It's working for my proposes until now.
But in this new server, I've a lot of files, and copy and recopy it all weeks will lost bandwidth and storage size.
I this old way, I can rollback files if something goes wrong just by week. In this new case I need to rollback files by day.
I'm thinking something like Time Machine on mac: I send just what is new, like rsync, but I can rollback (and travel to) each committed day.
To do this, I'm thinking to use a VCS, like Bazaar, to manage the commit entries. What do you think about this?
The second question about this strategy is to use a second backup storage: The Backup from Backup. I know data-centers like The Planet have RAID. But what happens if someone get access on my VPS and get the user and password from backup service stored on my CRON's backup script?
In my actually way, I'm doing two backups, and in my public server there isn't mention about the second storage. Again: what do you think about this? There are other ways?
Thank you, Daniel Koch
