Abstract
Data migrated from a deduplicated storage appliance are stored as cloud units at cloud storage. Each cloud unit includes containers including data containers storing segments of files, segment tree containers storing upper-level segments of segment trees representing the files, and cloud containers storing headers from the data and segment tree containers. A header for a data container includes fingerprints identifying the segments of files. A header for a segment tree container includes fingerprints identifying the upper-level segments. The cloud units are maintained in different states of accessibility including read-write, read-only, and offline. Upon detecting that local storage of the appliance does not have space to support a cloud unit in a read-write or read-only state, another cloud unit that is in a first state is selected, the first state being the read-write or read-only state. The selected cloud unit is placed in a second state, different from the first state.
