Snapshot And Backup Recovery

via “snapshot-based backup and recovery with point-in-time consistency”

Qdrant - High-performance, massive-scale Vector Database and Vector Search Engine for the next generation of AI. Also available in the cloud https://cloud.qdrant.io/

Unique: Implements snapshots using write-ahead logging to capture point-in-time consistency without requiring collection-wide locks, and snapshots include all indices (HNSW, field indices) so recovery is immediate without re-indexing

vs others: Faster recovery than re-indexing from raw data because snapshots include pre-built indices, and point-in-time consistency via WAL ensures no data loss unlike simple file-based backups
