Why does my deduplication ratio display as inf:1 in PHDVB 6.5?

SUMMARY

Information about deduplication reporting for active backups

ISSUE

When a deduplicated backup is performed, only new blocks of data are written to the storage location for each backup. Since this ratio is calculated while the backup is in progress, before any new data is written, the deduplication ratio is essentially infinite for the current virtual disk backup and is therefore displayed as a ratio of inf (infinite) to 1. When new data is encountered and written to disk, the deduplication ratio is updated.
