    Abstract: Capturing post-snapshot quiescence writes in a linear image backup chain. In one example embodiment, a method for capturing post-snapshot quiescence writes in a linear image backup chain may include taking a first snapshot of a source storage at a first point in time using a Volume Shadow Copy Service (VSS), identifying a first set of block positions of blocks that are allocated in the source storage at the first point in time, identifying a second set of block positions of blocks that are written to the first snapshot during post-snapshot quiescence of the first snapshot by the VSS or by one or more VSS writers, resulting in a first quiesced snapshot, copying the blocks in the first set from the first snapshot to a full image backup, and copying the blocks in the second set from the first quiesced snapshot to a first incremental image backup.

    Abstract: Detecting modifications to a storage that occur in an alternate operating environment. In one example embodiment, a method for detecting modifications to a storage that occur in an alternate operating environment may include tracking, in a modify map, modifications to a storage that occur during operation of a primary operating environment, identifying a first most recent transaction identifier in a journal of a file system of the storage prior to closing of the storage by the primary operating environment, upon opening of the storage by the primary operating environment, identifying a second most recent transaction identifier in the journal, determining that the second most recent transaction identifier does not match the first most recent transaction identifier, concluding that the storage was modified in an alternate operating environment between the closing and the opening of the storage by the primary operating environment, and invalidating the modify map.

    Abstract: Client-side encryption in a deduplication backup system. In one example embodiment, a method includes a backup phase in which various steps are performed for each allocated plain text block stored in a source storage. One step includes hashing, using a first cryptographic hash function, the plain text block to generate a first hash. Another step includes hashing, using a second cryptographic hash function, the first hash to generate a second hash. Another step includes searching a key-value table of a deduplication storage to determine whether the second hash matches any key in the key-value table. Another step includes, upon determining that the second hash does not match any key in the key-value table, encrypting, using an encrypt/decrypt function, the plain text block using the first hash as an encryption password and inserting a key-value pair into the key-value table with the key being the second hash and the value being the encrypted block.

    Abstract: Head start population of an image backup. In one example embodiment, a method for head start population of an image backup may include tracking blocks that are modified in a source storage between a first point in time and a second point in time, head start copying a first portion of the modified blocks into the image backup prior to the second point in time, activating a snapshot on the source storage at the second point in time where the snapshot represents a state of the source storage at the second point in time, and copying, subsequent to the second point in time, from the snapshot and into the image backup, a second portion of the modified blocks that were not yet copied into the image backup by the second point in time.

    Abstract: Avoiding encryption in a deduplication vault. In one example embodiment, a method may include analyzing an allocated plain text block stored in the source storage to determine if the block is already stored in the deduplication storage, in response to the block not being stored, encrypting the allocated plain text block and analyzing the encrypted block to determine if the encrypted block is already stored in the deduplication storage, analyzing a second allocated plain text block stored in the source storage to determine if the block is already stored in the deduplication storage, in response to the block already being stored, avoiding encryption of the second allocated plain text block by not encrypting the second allocated plain text block and instead associating the location of the second allocated plain text block in the source storage with the location of the duplicate block already stored.
