• Operations:

1. Backup current memory 2. Compress with optimal format 3. Update search index 4. Cleanup old files 5. Log results

Cleanup Schedule

• Daily at 04:00 UTC
• Operations:

1. Remove files older than RETENTION_DAYS 2. Archive logs 3. Optimize search index 4. Update statistics

Health Check Schedule
