MentisCell – Obsidian Vaults: Number of Vaults
Content
- 
Default practice: use a single vault for everything. 
- 
Rationale: - Life concepts are interconnected.
- Easier recovery and discoverability.
- Reduced friction when linking and reusing information.
 
- 
Exceptions where multiple vaults may be justified: - Different encryption keys.
- Segregating intellectual property (e.g., work vs personal).
- Sharing with tools that don’t support partial sharing.
- Sharing the entire vault (themes, automations, appearance).
 
- 
Drawbacks of multiple vaults: - No synchronization between them.
- Links don’t auto-update across vaults.
- Advanced URI plugin mitigates some issues, but not fully.
 
- 
Personal practice: - Always a single vault.
- Corporate data remains on corporate devices/software.
- Vault name: Area51 (origin: early internet presence on Geocities).
 
Essence
- Single vault = best practice.
- Multiple vaults only in rare, justified cases.
- Corporate vs personal separation is organizational, not technical.
