Abstract: The described embodiments set forth techniques for providing a backup progress estimate for a backup of a source file system volume (FSV). The techniques involve determining, for the source FSV, a backup size during performance of backup operations. The operations can include determining the backup size based on a number of files on the source FSV. Additionally, the operations can include copying files of the source FSV and/or propagating corresponding files of a destination FSV to a location of the backup of the source FSV on a destination storage device and updating one or more metrics using a number of files and/or a number of bytes copied and/or propagated to the backup. In this manner, a progress indication for the backup may be determined based on the one or more metrics responsive to files and/or directories of the source file system volume being stored on a destination storage device.
