Abstract

Techniques are provided for multi-cloud data protection using threshold-based file reconstruction. One method comprises obtaining a file comprising metadata and data for storage in a cloud environment; generating a plurality of encrypted file portions from the data; and uploading each of the encrypted file portions with the metadata as cloud objects to multiple different cloud environments. A threshold number of the encrypted file portions are needed from at least two different cloud environments to reconstruct the file. For file reconstruction, the threshold number of encrypted file portions can be validated, merged and decrypted.
