SYSTEMS AND METHODS FOR DYNAMIC DATA BACKUP

摘要

In a computer network that includes database mirroring, a first database (206) is located on a first database server (202) and a second database (208) is located on a second database server (204) and, optionally, a witness database server (222) One of the first database (206) or the second database (208) is a live database while the other database is the mirror database A process is initiated for communicating with the first database server (202), the second database server (204), or the witness database server (222), to determine which of the first database or the second database is the live database The location of the live database is determined by reading information from the table entries in system databases (210, 212) on either the first or second database servers, or the optional witness database server (222), and a backup operation is performed wherein the live database is backed up.
