take a while to restore a PB and a way to take a hot backup without impacting the service that by itself is a task or snapshots which is more disk

Depending on the amount of writes could be a ton of extra disk and a bucket for network cost
- bayindirh 2y agoThese systems support zero-downtime snapshots. You tell it to snapshot, it instantly snapshots, you can run a differential/incremental backup at great speeds. Your RAID controller is already caching the hot data, so the impact is minimal. Except network cost there's no extra disk required. It's just broadcasted writes consumed on the other hand. These boxes are not dumb JBODS. They support their own replication/backup subsystems, so everything is transparent.
