Abstract
Embodiments are described for performing a storage tier-specific file system operation in a file system that comprises a namespace that spans multiple tiers of storage. A file system command can be a tier-specific deletion of files in a multi-tier file system, or a move data operation from a first tier of storage to a second tier of storage, affecting both the first and second tier of storage. The file system command can generate a copy of the namespace for the first tier of storage and a snapshot of the data of the first tier of storage referenced in the file system operation. Functionality may be performed using one or more storage appliances, each of which can have its open processing system, memory and storage device(s). Storage tiers can include active tier, cloud tier, and remote or archive storage tier.
