Logbac
Logbac is a term used in information technology to describe systems that rely on log-centric data management, where event data is recorded in append-only logs to support backup, auditing, and recovery. The term is not tied to a single product but covers a family of approaches that emphasize immutability, traceability, and time-based restoration. In this context, a logbac architecture stores changes as sequential log records and uses versioning, checksums, and cryptographic chaining to ensure data integrity.
Key concepts include append-only logging, time-stamped entries, and verifiable restoration. Log compaction and indexing are commonly
Applications of logbac concepts include disaster recovery, auditing, compliance, event-sourced systems, and data lineage in cloud
Challenges associated with logbac approaches involve managing the growth of log data, ensuring low-latency write paths,
