EXCLUDING FILE SYSTEM OBJECTS FROM RAW IMAGE BACKUPS

摘要

Techniques associated with excluding file system objects from raw image backups are described in various implementations. In one example, a method may include generating a virtual volume that comprises a replica of a source volume to be backed up, and providing file system access to the virtual volume. The method may also include receiving file system commands to remove specified file system objects from the virtual volume, and storing modified blocks that result from the file system commands to remove the specified file system objects. The method may also include performing a raw image backup to back up the source volume using unmodified blocks from the source volume and the stored modified blocks, such that the raw image backup excludes the specified file system objects.

1. A method comprising:
generating, using a computing system, a virtual volume that comprises a replica of a source volume to be backed up; providing, using the computing system, file system access to the virtual volume; receiving, using the computing system, the system commands to remove specified file system objects from the virtual volume; storing, using the computing system, modified blocks that result from the file system commands to remove the specified file system objects from the virtual volume; and performing, using the computing system, a raw image backup to back up the source volume using unmodified blocks from the source volume and the stored modified blocks, such that the raw image backup excludes the specified file system objects.
