Abstract

Methods, systems, and devices for data management are described. Versioned metadata associated with a computing object may be stored in nonvolatile memory. The computing object may be represented as a portioned group that includes multiple portions of the computing object. The versioned metadata may be stored in a first metadata chain for the portioned group and respective metadata chains for the multiple portions. The versioned metadata may be transferred to an archival storage system, which may involve writing serialized metadata in the first metadata chain and the respective metadata chains to a local file one at a time. The serialized metadata for a metadata chain may be removed from volatile memory before all the versioned metadata has been loaded into the volatile memory. The local file may be written to the archival storage system after all the versioned metadata has been written to the local file.

Claims20

Dependent claims

A method, comprising:

storing, in nonvolatile memory, versioned metadata associated with a computing object, wherein the computing object is represented as a portioned group comprising a plurality of portions of the computing object, and wherein the versioned metadata is stored in a first metadata chain for the portioned group and respective metadata chains for respective portions of the plurality of portions;
and
transferring, to an archival storage system, the versioned metadata for the computing object, wherein transferring the versioned metadata comprises:
writing serialized metadata in the first metadata chain and the respective metadata chains to a local file, wherein one metadata chain is written to the local file at a time, and wherein serialized metadata for a metadata chain is removed from volatile memory before all the versioned metadata has been loaded into the volatile memory, and
writing the local file to the archival storage system after all the versioned metadata has been written to the local file.

2 more elements

A data management system, comprising:

one or more memories;
and
one or more processors, wherein the one or more memories store code comprising instructions executable, individually or collectively, by the one or more processors to cause the data management system to:
store, in nonvolatile memory, versioned metadata associated with a computing object, wherein the computing object is represented as a portioned group comprising a plurality of portions of the computing object, and wherein the versioned metadata is stored in a first metadata chain for the portioned group and respective metadata chains for respective portions of the plurality of portions;
and
transfer, to an archival storage system, the versioned metadata for the computing object, wherein the instructions for transferring the versioned metadata are executable by the one or more processors to cause the data management system to:
write serialized metadata in the first metadata chain and the respective metadata chains to a local file, wherein one metadata chain is written to the local file at a time, and wherein serialized metadata for a metadata chain is removed from volatile memory before all the versioned metadata has been loaded into the volatile memory, and
write the local file to the archival storage system after all the versioned metadata has been written to the local file.
