Abstract

There is provided a method for optimizing a data backup. The method comprising determining a backup project size, the backup project size identifying the quantity of data to be backed up; detecting available recording devices for transferring the data backup to storage media; receiving an input corresponding to at least one user specified optimization variable, wherein the at least one user specified optimization variable comprises an upper limit on the length of each of the calculated plurality of data streams; utilizing the at least one user specified optimization variable to calculate a plurality of data streams for performing the data backup; and assigning subsets of the plurality of data streams to the available recording devices to optimize the data backup.

Claims

1. A method for optimizing a data backup, the method comprising:

determining a backup project size, the backup project size identifying the quantity of data to be backed up;

detecting available recording devices for transferring the data backup to storage media;

receiving an input corresponding to at least one user specified optimization variable, wherein the at least one user specified optimization variable comprises an upper limit on the length of each of the calculated plurality of data streams;

utilizing the at least one user specified optimization variable to calculate a plurality of data streams for performing the data backup; and

assigning subsets of the plurality of data streams to the available recording devices to optimize the data backup.

2. The method of claim 1, further comprising confirming that the at least one user specified optimization variable is within a predetermined allowable range.

3. The method of claim 1, wherein the data backup is implemented for a storage area network (SAN).

4. The method of claim 1, wherein the at least one user specified optimization variable limits the maximum time duration of each of the calculated plurality of data streams.

5. The method of claim 1, wherein the at least one user specified optimization variable comprises a lower limit on the length of each of the calculated plurality of data streams.

6. The method of claim 5, wherein the at least one user specified optimization variable sets the minimum quantity of data contained by each of the calculated plurality of data streams.

7. The method of claim 5, wherein the available recording devices are tape drives.

8. A computer-readable medium having stored thereon instructions comprising a backup optimization application which, when executed by a computer controlled backup library, perform a method for optimizing data backup, the computer-readable medium comprising:

code for determining a backup project size, the backup project size identifying the quantity of data in a data backup;

code for detecting available recording devices for transferring the data backup to storage media;

code for receiving an input corresponding to at least one user specified optimization variable, wherein the at least one user specified optimization variable comprises an upper limit on the length of each of the calculated plurality of data streams;

code for utilizing the at least one user specified optimization variable to calculate a plurality of data streams for performing the data backup; and

code for assigning subsets of the plurality of data streams to the available recording devices to optimize the data backup.

9. The computer-readable medium of claim 8, wherein the computer controlled backup library is implemented for a storage area network (SAN).

10. The computer-readable medium of claim 8, wherein the at least one user specified optimization variable limits the maximum time duration of each of the calculated plurality of data streams.

11. The computer-readable medium of claim 8, wherein the at least one user specified optimization variable comprises a lower limit on the length of each of the calculated plurality of data streams.

12. The computer-readable medium of claim 11, wherein the at least one user specified optimization variable sets the minimum quantity of data contained by each of the calculated plurality of data streams.

13. The computer-readable medium of claim 8, wherein the available recording devices are tape drives.

utilize the at least one user specified optimization variable to calculate a plurality of data streams for performing the data backup; and

assign subsets of the plurality of data streams to the available recording devices to optimize the data backup.

15. The system of claim 14, the data backup is implemented for a storage area network (SAN).

16. The system of claim 14, wherein the at least one user specified optimization variable utilized by the backup optimization application limits the maximum time duration of each of the calculated plurality of data streams.

17. The system of claim 14, wherein the at least one user specified optimization variable utilized by the backup optimization application comprises a lower limit on the length of each of the calculated plurality of data streams.

18. The system of claim 17, wherein the at least one user specified optimization variable utilized by the backup optimization application sets the minimum quantity of data contained by each of the calculated plurality of data streams.
