Came across this fantastic utility that is completely FOSS. Intent was to upgrade my smaller SSD to 1TB. Stumbled upon foxclone.com

Experts from the site :

"FoxClone is a Linux based image backup, restore and clone tool using a simple point and click interface. Booted from its' own linux system, it takes images of the partitions on your hard disk (HDD) or solid-state drive (SSD) and stores them for later restoration. Image files can optionally be compressed to save space."

The software worked blazingly fast as SSD's were employed at both ends that too without a single error! I booted from the new SSD and was blown away with the ease of overall process.

The creator of the software has declined my request to reimburse in any way possible. Hence I'm sharing it with HN for all Linux users.
