    Abstract: First partial baseline data of a first storage system is identified. First changed data of the first storage system is identified. The first changed data comprises data that has changed since a previous point in time. First backup data is written to a second storage system. The first backup data comprises the first partial baseline data and the first changed data. After writing the first backup data to the second storage system, second partial baseline data of the first storage system is identified. The second partial baseline data does not include the first partial baseline data. Second changed data of the first storage system is identified. The second changed data comprises data that has changed since writing the first backup data. Second backup data is written to the second storage system. The second backup data comprises the second partial baseline data and the second changed data.

    Abstract: Systems and methods for creation and retention of immutable snapshots to facilitate ransomware protection are provided. According to one embodiment, multiple use cases for retention of snapshots are supported, including (i) maintaining a locked snapshot on a source volume of a first storage system on which it was originally created for at least an associated immutable retention time; (ii) replicating the locked snapshot to a destination volume of a second storage system and also maintaining the replica of the locked snapshot on the destination volume for at least the associated immutable retention time; and (iii) maintaining an unlocked snapshot on the source volume, replicating the unlocked snapshot to the destination volume, locking the replicated snapshot on the destination volume when it has an associated non-zero immutable retention time, and thereafter maintaining the replica on the destination volume in accordance with the immutable retention time.

    Abstract: A backup tool can manage multi-level backup into a cloud and restoration from the cloud. The backup tool can request a data source to stream backup data to the backup tool, and the backup tool can then generate data objects from the data stream for storing into the cloud. The backup tool generates the data objects in accordance with serialization of the data stream. The order of the data objects resulting from the data stream serialization is encoded into the names of the data objects. In addition, the backup tool encodes the backup level into the object names. With sequencing and backup level encoded into the data object names, the data objects can be stored in the cloud for later restoration.

    Abstract: One or more techniques and/or computing devices are provided for restarting a dump backup. For example, a phase offset table is used to track a directory transfer phase offset and a file transfer phase offset of phases of a dump backup. An offset map is used to map inodes, of data being backed up, to offsets within a backup image within which the data is being backed up. The phase offset table and/or the offset map are evaluated using a bytes written value to identify a phase during which the dump backup aborted and to identify a restart point. Accordingly, the dump backup is restarted at the restart point. In this way, the dump backup may be restarted during any phase and/or at any point using the bytes written value, the phase offset table, and the offset map without the need for additional information such as a file history.
