Backup Recording for Live Events, Done Properly
Running a second, independent recording of live audio so a single failure does not lose the event.
Tomas Lindqvist
At a glance
- Redundancy a second recorder captures the same feed independently
- Power backup devices should not share a single power source
- Media recording to two cards protects against card failure
- Monitoring someone should watch levels throughout
Why it matters
Why it matters: Live audio cannot be repeated, and recorders, cards and cables all fail eventually.
Best practice
- Record a backup on separate equipment
- Use different power sources
- Use dual-card recording where available
- Check both recordings during the event
- Copy and verify files before leaving
Common pitfalls
Watch out for:
- A single recorder for irreplaceable events
- Both recorders on one power strip
- Unchecked recordings
- Formatting cards before verification
When to call in a specialist
Bottom line Bring in help when recording conferences or one-off performances.
