Abstract
Systems and methods for duplication avoidance are disclosed. In one implementation, a VM can receive a request to perform a file access operation with respect to a file and determine a hash value corresponding to a content of the file. The VM can search the file identified by the hash value in in a host file system. Responsive to failing to find the hash value in the host file system, the VM can search the hash value in a guest file system of the VM and responsive to finding the file identified by the hash value in the guest file system, can perform the file access operation with respect to the file.
