SnapshotIQ can create unlimited snapshots on a cluster. This provides a substantial benefit over most other snapshot implementations because the snapshot intervals can be far more granular and so offer improved RPOs.
SnapshotIQ has several fundamental differences as compared to most snapshot implementations. The most significant of these are, first, that OneFS snapshots are per directory based. This is in contrast to the traditional approach, where snapshots are taken at a file system or volume boundary. Second, since OneFS manages and protects data at the file-level, there is no inherent, block-level indirection layer for snapshots to use. Instead, OneFS takes copies of files, or pieces of files (logical blocks and inodes) in a logical snapshot process.
