Pathname translation in a data replication system
First Claim
1. A method for performing pathname translation in a data replication system, the method comprising:
- processing a log entry from a log file associated with a source system with one or more computer processors, wherein the log entry identifies a data management operation associated with an inode wherein the inode is a child of one or more parent inodes;
obtaining path data for the inode from a database associated with the data replication system comprising a first short inode name and a parent inode identifier associated with the one or more parent inodes;
obtaining a second short inode name associated with the parent inode identifier from the database;
constructing from at least the first and second short inode names, path data comprising an absolute pathname that corresponds to the inode; and
storing the absolute pathname and the data management operation associated with the log entry on a destination system.

Abstract
Performing data management operations on replicated data in a computer network. Log entries are generated for data management operations of an application executing on a source system. Consistency point entries are used to indicate a time of a known good, or recoverable, state of the application. A destination system is configured to process a copy of the log and consistency point entries to replicate data in a replication volume, the replicated data being a copy of the application data on the source system. When the replicated data represents a known good state of the application, as determined by the consistency point entries, the destination system(s) may perform a storage operation (e.g., snapshot, backup) to copy the replicated data and to logically associate the copied data with a time information (e.g., time stamp) indicative of the source system time when the application was in the known good state.

10. A system for performing pathname translation during data replication in a computer network, the system comprising:
-
a log file of log entries associated with a source system; at least a first log entry in the log file system identifying at least one inode on the source system and at least one data management operation, wherein the inode has one or more parent inodes; and a module executing in one or more computer processors that is configured to obtain path data for the inode from a database associated with the data replication system comprising a first short inode name and a parent inode identifier for the one or more parent inodes, wherein the module is further configured to obtain a second short inode name associated with the parent inode identifier from the database and construct an absolute pathname from at least the first and second short inode names that corresponds to the inode, and wherein the module is further configured to store the data management operation and the absolution pathname on a destination system. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
