One or more objects associated with a source storage is determined to be archived to a remote storage. A corresponding minimum expiration time is stored in nodes of a tree data structure associated with an archive that represents the archived data associated with the source storage. At least a portion of the tree data structure associated with the archive is traversed to identify one or more nodes associated with one or more archived objects having a corresponding expiration time expiring before an expiration time associated with the archive.

Managing expiration times of archived objects

Techniques are described for selectively extending a WORM lock expiration time for a chunkfile. An example method comprises identifying, by a data platform implemented by a computing system, a chunkfile that includes a chunk that matches data for an object of a file system; determining, by the data platform after identifying the chunkfile, whether to deduplicate the data for the object of the file system by adding a reference to the matching chunk, wherein determining whether to deduplicate the data comprises applying a policy to at least one of a property of the chunkfile or properties of one or more of a plurality of chunks included in the chunkfile; and in response to determining to not deduplicate the data for the object of the file system, causing a new chunk for the data for the object of the file system to be stored in a different, second chunkfile.

Adaptive deduplication of data chunks

An amount of expiration time extension for one or more objects associated with a first archive of a first snapshot of a source storage is determined based at least in part on a second data management policy associated with a second archive and one or more dynamically determined metrics. The first archive that includes the one or more objects is caused to be stored to a remote storage. At least a portion of content of the first archive is referenced by data chunks stored in a first chunk object of the remote storage and the first archive is associated with a first data management policy. Based on the determined amount of expiration time extension, an expiration time for the one or more objects associated with the first archive is stored in an archive metadata of the one or more objects associated with the first archive.
