We would like to outsource backup of our KVM VPSes. We have a few requirements:
1. Access to snapshots of the last 30 days with single day granuality.
2. Backup has to be encrypted.
We have 7 full servers with over 100 vpses.
- cool_username 9y agoNot looking to do work for you, just a tip. Look into ZFS. Daily snapshot, incremental etc? No problem. However something you'll need to think about if you're snapshotting - do you need to snapshot the memory state/disk buffers too? e.g. a database. Or anything where the total state of the VM is split between disk and CPU/memory. If the answer is no this is an easy problem to solve. If the answer is 'yes' life gets more complicated.
- agsamek 9y agoWe manage this somehow. The issue here is that taking snaphshot is only a part of the problem. Then there is transfering data, managing it, retention, hard drive management and so on. And we don't see competitive advantage here. We just need this requirement to be fulfilled.
