System and method for identifying block-level write operations to be transferred to a secondary site during replication
First Claim
1. A method, comprising:
- generating a block-level write operation, wherein the block-level write operation causes a value to be written to a region of a primary volume;
identifying whether the region of the primary volume stores a first type of a plurality of types of file system metadata; and
generating information indicative of whether any of the block-level write operation should be transferred to a secondary site during replication of data in the primary volume, wherein if the region of the primary volume stores the first type of file system metadata, the information identifies that less than all of the block-level write operation should be transferred to the secondary site.

Abstract
A method involves generating a block-level write operation, which causes a value to be written to a primary volume, and generating information indicative of whether any of the block-level write operation should be transferred to a secondary site during replication of data in the primary volume. The information can indicate that all, part, or none of the block-level write operation should be transferred to the secondary site. If the information indicates that less than all of the block-level write operation should be transferred to a secondary site, the information can also indicate that logical information associated with the block-level write operation should be transferred to the secondary site instead of transferring the value being written by the block-level write operation.

12. A system comprising:
-
a processor; and a memory coupled to the processor, wherein the memory stores program instructions executable by the processor to; generate a block-level write operation, wherein the block-level write operation causes a value to be written to a region of a primary volume, identify whether the region of the primary volume stores a first type of a plurality of types of file system metadata, and generate information indicative of whether all of the block-level write operation should be transferred to a secondary site during replication of data in the primary volume, wherein if the region of the primary volume stores the first type of file system metadata, the information identifies that less than all of the block-level write operation should be transferred to the secondary site. - View Dependent Claims (13, 14)

15. A computer readable medium comprising program instructions executable to:
-
generate a block-level write operation, wherein the block-level write operation causes a value to be written to a region of a primary volume, identify whether the region of the primary volume stores a first type of a plurality of types of file system metadata, and generate information indicative of whether all of the block-level write operation should be transferred to a secondary site during replication of data in the primary volume, wherein if the region of the primary volume stores the first type of file system metadata, the information identifies that less than all of the block-level write operation should be transferred to the secondary site. - View Dependent Claims (16, 17)

18. A system comprising:
-
means for generating a block-level write operation, wherein the block-level write operation causes a value to be written to a region of a primary volume, means for identifying whether the region of the primary volume stores a first type of a plurality of types of file system metadata, and means for generating information indicative of whether all of the block-level write operation should be transferred to a secondary site during replication of data in the primary volume, wherein if the region of the primary volume stores the first type of file system metadata, the information identifies that less than all of the block-level write operation should be transferred to the secondary site.
