Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
114 words
A method of transferring data that maintains data integrity, the method comprising: setting metadata associated with the data to indicate initiation of a transfer of the data; transferring the data from a data system to a file system; determining whether the transfer of the data was successful; setting the metadata to indicate the successful transfer in response to the determination that the transfer of the data was successful; setting the metadata to indicate initiation of a deletion of the data; deleting the data; determining whether the deletion of the data was successful; and setting the metadata to indicate the successful deletion in response to the determination that the deletion of the data was successful.
Claim 2
Independent Claim
114 words
A method of transferring data that maintains data integrity, the method comprising: setting metadata associated with the data to indicate initiation of a transfer of the data; transferring the data from a data system to a file system; determining whether the transfer of the data was successful; setting the metadata to indicate the successful transfer in response to the determination that the transfer of the data was successful; setting the metadata to indicate initiation of a deletion of the data; deleting the data; determining whether the deletion of the data was successful; and setting the metadata to indicate the successful deletion in response to the determination that the deletion of the data was successful.
Claim 3
Dependent Claim
31 words
The method of claim 1 further comprising transferring the data from the data system to the file system in response to the determination that the transfer of the data was unsuccessful.
Claim 4
Dependent Claim
25 words
The method of claim 1 further comprising initiating an error handling process in response to the determination that the transfer of the data was unsuccessful.
Claim 5
Dependent Claim
22 words
The method of claim 1 further comprising deleting the data in response to the determination that the deletion of data was successful.

Claim 11
Dependent Claim
13 words
The method of claim 1 further comprising using filters when transferring the data.
Claim 12
Independent Claim
127 words
A system for transferring data that maintains data integrity, the system comprising: a file system; a data system configured to transfer the data to the file system and delete the data; and a management system configured to set metadata associated with the data to indicate initiation of a transfer of the data, determine whether the transfer of the data was successful, set the metadata to indicate a successful transfer in response to a positive determination that the transfer of the data was successful, set the metadata to indicate initiation of a deletion of the data, determine whether the deletion of the data was successful, and set the metadata to indicate the successful deletion in response to a positive determination that the deletion of the data was successful.
Claim 13
Independent Claim
127 words
A system for transferring data that maintains data integrity, the system comprising: a file system; a data system configured to transfer the data to the file system and delete the data; and a management system configured to set metadata associated with the data to indicate initiation of a transfer of the data, determine whether the transfer of the data was successful, set the metadata to indicate a successful transfer in response to a positive determination that the transfer of the data was successful, set the metadata to indicate initiation of a deletion of the data, determine whether the deletion of the data was successful, and set the metadata to indicate the successful deletion in response to a positive determination that the deletion of the data was successful.
Claim 14
Dependent Claim
32 words
The system of claim 11 wherein the data system is configured to transfer the data to the file system in response to the determination that the transfer of the data was unsuccessful.
Claim 15
Dependent Claim
28 words

Claim 17
Dependent Claim
19 words
The system of claim 11 wherein the metadata comprises a state flag that indicate a state of the data.
Claim 18
Dependent Claim
18 words
The system of claim 11 wherein the metadata comprises a state flag that indicate copies of the data.
Claim 19
Dependent Claim
24 words
The system of claim 16 wherein the management system is configured to process the metadata to determine where the copies of the data resides.
