A data file is encrypted with a file-specific encryption key and sent to a remote data storage system. The file-specific encryption key is encrypted with a master key. The encrypted file-specific encryption key and the master key are both stored remotely from the encrypted file and they are stored remotely from one another.

Securely storing data in a data storage system

The concepts relate to data handling, and more specifically to data handling scenarios where data is revised on one computer and stored on another computer. One example can obtain a set of blobs relating to revisions of a file. The example can determine a target size of datastore blobs. In an instance where a total size of the set of blobs is less than the target size, this example can aggregate the set of blobs into an individual datastore blob. Otherwise, the example can identify new or edited individual blobs of the set and aggregate the new or edited individual blobs into first datastore blobs. The example can also aggregate other individual blobs of the set into second datastore blobs.

Data handling

Data to be moved from a source system to a target system, for a set of tenants, is first identified. The data is enumerated by a first computing instance in the source system to obtain an enumeration list. Data is copied from the source system to the target system based on the enumeration list by a second computing instance. The data in the source and target systems is then enumerated by a third computing instance to determine whether any data is still to be moved and another enumeration list is generated. The data still to be moved is then moved based on the other enumeration list.
