Abstract
A method and system for copying backup data is disclosed. Backup data may be copied to a first virtual tape library in the same format as it would be copied to a physical tape library. The backup data may also be electronically copied to a second virtual tape library or to a physical tape library.
Claims22
A method for copying backup data comprising:
- copying backup data from a data protection application to an on-site virtual tape library wherein the data protection application writes to the virtual tape library as if it were writing to a physical tape library;
- wherein a log is kept of all the write operations made while the data is copied to the on-site virtual tape library in order to create additional copies without the use of the data protection application;
- and
- electronically transmitting the data from the on-site virtual tape library to an off-site storage medium, wherein a restore operation may be performed using the data transmitted to the off-site storage medium.

A method for copying backup data comprising:
- copying backup data from a data protection application to an on-site virtual tape library wherein the data protection application writes to the virtual tape library as if it were writing to a physical tape library;
- selecting a criteria for transmitting data from the on-site virtual tape library to an off-site virtual tape library;
- wherein a log is kept of all the write operations made while the data is copied to the on-site virtual tape library in order to create additional copies without the use of the data protection application and
- electronically transmitting the data from the on-site virtual tape library to the off-site virtual tape library according to the selected criteria, wherein a restore operation may be performed using the data transmitted to the off-site virtual tape library.
1 more element
A system for copying backup data comprising:
- an on-site virtual tape library for storing backup data wherein a data protection application copies the data to the on-site virtual tape library as if the data protection application was copying the data to a physical tape library;
- wherein a log is kept of all the write operations made while the data is copied to the on-site virtual tape library in order to create additional copies without the use of the data protection application;
- means for electronically transmitting the data from the on-site virtual tape library to an off-site storage medium;
- the off-site storage medium being selected from the group of;
- a virtual tape library;
- and
- a physical tape library;
- and
- wherein a restore operation may be performed using the data transmitted to the off-site storage medium.
