More mistakes(2)
Handle with care. Do not confuse backup (noun/verb for data copies) with back up (phrasal verb meaning support or reverse). Also, backup is not interchangeable with restore or recover, which are separate processes.
- ✕The backup restored all our files automatically.✓We restored all our files from the backup automatically.
Backup is the copy itself; restore is the action of recovering from it. The backup does not restore; you restore from a backup.
- ✕We have many backups but no backup strategy.✓We have many backups but no backup plan or retention policy.
In context, 'strategy' can be vague. Use 'plan', 'policy', or 'procedure' to be more specific about what is missing.
