Clients sometimes arrive with backup descriptions like “main phrase” or “wife’s copy” written on masking tape. Those labels age poorly and reveal too much to anyone opening the cabinet.
The B-series convention
Backup media receive B-codes independent of device W-codes. A printed map entry reads: B-02 → C-01-S3-P2 → pairs with W-01. The label on the pouch shows only B-02.
Tamper-evident seals
We use numbered seals that fracture on removal. During annual reviews we replace seals even if pouches were not opened — adhesive fatigue is real.
Split backups
Shamir shards or split envelopes get subcodes: B-03a and B-03b stored in different cabinets. The map states both must be retrieved for recovery; rehearsal visits test whether household members know both locations.
Common mistakes
Writing partial words (“first four letters”) on labels. Storing photos of envelopes in phone galleries. Matching device serial numbers to seed content in Notes apps. We retire these practices during mapping without scolding — the goal is a workable map.
