Rust-native Bacula File Daemon plugin engineered for HPC workloads: parallel filesystems (Lustre, GPFS / IBM Spectrum Scale, BeeGFS, CephFS, WekaFS), billion-file namespaces, Slurm/PBS job-aware scheduling and AI/ML checkpoint-aware deduplication. Replaces the FD's single-threaded walker with a work-stealing parallel walker and adds namespace sharding to saturate the HPC fabric.
What it does
- Parallel namespace walker — Work-stealing rayon walker, one worker per Lustre MDT / GPFS NSD / BeeGFS metadata target — 10-100× the metadata throughput of the stock FD.
- Namespace sharding — Shard=N/M splits the namespace into N shards (hash-of-inode or subtree pinning); N concurrent Bacula jobs yield N outbound SD streams.
- Filesystem-native incrementals — Lustre ChangeLogs, GPFS mmapplypolicy, CephFS rstats+rctime, BeeGFS metadata-shard scan — "changed since" without billion stat() calls.
- Stripe-aware reader + restripe-on-restore — Reads Lustre OSTs in parallel via llapi_layout; persists original layout as a RestoreObject and recreates striping on restore.
