Storage-Data management
- snapshots - fastest, not really a “backup”
- copies settings and metadata necessary to restore your data in case of a disruption.
- The actual data files need to be stored separately to be retrievable
- replications - fastest, reliable, but resource hungry
- what?
- quick and easy resumption of operations after an outage or corruption
- replicate everything
- types
- Async - Every X time, duplicate in other system
- Sync - On every change, duplicate in other system
- multi-site - multiple geographical locations/machin
- snapshot
- like normal snapshots but are
- portable
- can use the same snapshot and bring it to another machine/system
- log shipping - mostly used for SQL logging redundancy & recovery
- full backup - slowest, most reliable, no resource hungry
- types
- full - complete copy, classic backup
- differential - Backs up changes made since last full backup (regardless of any incremental backups that occurred in the meantime)
- incremental - backs up changes made since last backup (full and incremental)
