Patent ID: 7529745

Claim:
A method for verifying preservation of metadata comprising: migrating a file from a source filesystem, stored upon a storage device, to a destination filesystem, wherein said source filesystem and said destination filesystem are maintained on different storage systems; automatically comparing metadata said file transferred from said source filesystem location with metadata of said file at said destination filesystem location, including: determining time resolution of each of said filesystems and setting a time resolution flag if time resolution of each of said filesystems do not match; comparing creation time of said file at each of said filesystems and setting a creation time flag if creation time of each of said filesystems do not match; and comparing a last write time of said file at each of said filesystem and setting a last write time flag if last write time of each of said filesystems do not match; determining if said metadata of said file from said source filesystem is equivalent to said metadata of said file at said destination filesystem; compiling a list of metadata transfer failures, including mismatch flags; and transmitting all flags to an operator indicating a source of error responsive to a difference in said metadata in two copies of the migrated file.
