Optimize firecracker snapshot storage #1096
Description
Is your feature request related to a problem? Please describe.
Snapshot storage currently consumes a significant amount of space, especially due to large memory files. This becomes problematic when storing multiple snapshots remotely, leading to increased storage costs and slower transfers.
Describe the solution you'd like
Introduce optimizations to reduce the size of snapshot memory files before uploading them to remote storage. This could include:
- Compression (e.g., zstd)
- Deduplication strategies across memory files of similar VMs or repeated snapshots
This should aim to reduce storage footprint without adding significant overhead to the snapshot creation or restoration process.
Additional context
This work follows up on remote snapshot support introduced in issue #823 .
