Techniques are described for performing direct archive of data chunkfiles. A computing system comprising a storage device and processing circuitry having access to the storage device may be configured to perform various aspects of the techniques. The processing circuitry may be configured to predict an incoming data rate of native format to be archived to obtain a predicted incoming data rate for the native format data to be archived, and compare the predicted incoming data rate to a first threshold data rate. The processing circuitry may also be configured to, responsive to determining that the predicted incoming data rate exceeds a first threshold data rate, segment the native format data into chunks, and directly write the chunks to an archive storage system as a chunkfile.

Adaptive archive of data chunkfiles

A plurality of logical storage segments of storage drives of a plurality of storage nodes are identified. At least one of the storage nodes includes at least a first logical storage segment and a second logical storage segment included in the plurality of logical storage segments. A distributed and replicated data store using a portion of the plurality of logical storage segments that excludes at least the second logical storage segment is provided. An available storage capacity metric associated with the plurality of logical storage segments is determined to meet a first threshold. In response to the determination that the available storage capacity metric meets the first threshold, at least the second logical storage segment is dynamically deployed for use in providing the distributed and replicated data store in a manner that increases a storage capacity of the data store while maintaining a fault tolerance policy of the distributed and replicated data store.
