System and method for synchronization of data containers

A method of managing data storage on a plurality of storage elements, the method comprising:

• receiving, at a first timing, a first version of a data element associated with a logical address;
• computing a first URV based on content of the first version;
• storing the first version on a first storage element;
• receiving, at a second timing, at least one second version of the data element associated with the logical address;
• computing at least one second URV based on content of the at least one second version;
• storing the at least one second version on at least one second, respective storage element;
• receiving a data access request comprising the logical address;
• selecting between the first version and the at least one second version based on at least one of:
• the first URV, the at least one second URV, the first timing and the second timing;
• and
• responding to the received data access request based on the selected version.

A method of synchronizing content of a data storage system, the method comprising:

• receiving at least one data element;
• computing a URV based on a content of the at least one data element;
• storing copies of the at least one data element on a plurality of CAS devices according to the URV;
• maintaining a TCR, comprising one or more entries, wherein each entry corresponds to a stored copy of a data element and comprises a mapping of a logical address of the stored copy to a respective URV;
• comparing between contents of one or more TCR entries to determine a condition in which a content of the stored copies of the at least one data element has diverged over time;
• and
• synchronizing content of the at least one stored copy of a data element between a first CAS device and one or more second CAS devices based on the comparison.

A system for synchronizing between content of a first data container and content of at least one second data container, the system comprising:

• a non-transitory memory device, one or more modules of instruction code stored in the non-transitory memory device, and a processor associated with the non-transitory memory device and configured to execute the one or more modules of instruction code, wherein upon execution of said one or more modules of instruction code, the processor is further configured to:
• receive one or more first data elements of the first data container and one or more second data elements of the at least one second data container;
• compute one or more first URVs for the respective one or more first data elements and compute one or more second URVs for the respective one or more second data elements;
• store the one or more first data elements on a first storage element and store the one or more second data elements at a second storage element;
• compare between a first URV of the one or more first URVs and a second URV of the one or more second URVs to identify data elements having diverged content;
• and
• synchronize between content of the first data container and content of the at least one second data container based on said comparison.
