After setting up preseeding boot options, the biggest speed bottleneck with Clonezilla for me is the boot speed of the Clonezilla (Debian) itself. I run Clonezilla on dozens of machines each month (most individually, cannot do multicasts because we're a custom PC builder and our builds use different images), and each time it takes a while to boot up Clonezilla from the USB stick. I know it's not "that" slow, but considering the fact that nowadays a SSD boots up a full Windows in like 15 seconds from button press, the boot speed of Clonezilla on USB is becoming a bit painful to endure.
So I would like to know what's the best way to boot Clonezilla as fast as possible? I believe a SSD can do a great job, but getting an internal one in and out is not an option. Externally, USB is the only port that every machine has. Will an expensive and faster USB drive make things much better? What about one of those USB SSD enclosures? What's the speed of the PXE Clonezilla booting like?
Your advice will be greatly appreciated.
How many secs does it boot on your machine?
For sure a faster USB drive will boot faster. USB SSD enclosure might do a good job, too.
PXE booting really depends. Maybe it will be faster, but maybe due to slow connection and negotiation, it's even slower.
Thanks for the response. This forum seems very inactive which is surprising to me given the popularity of Clonezilla.
I didn't do a countdown yet but it was definitely longer than the 15-20 second it takes to boot up a Windows OS on SSD! Maybe I'm a bit spoiled by my own highly optimized machine which boots into full Windows 8.1 desktop by 10 seconds.
At this time we only have some "regular" USB 3.0 thumb drives. I've ordered a Corsair and a Sandisk high-end stick and will see if it makes a difference. These're supposed to be as fast USB 3.0 can go, and are really just like SSD's in a USB's body.
I have a feeling that PXE will be slow too, and a quick search on Google seems to return many complaints about slow PXE boots (though unrelated to Clonezilla). Makes me hesitate to spend the effort to experiment.
I didn't count
To use USB 3.0 booting, first you have to make sure your USB 3.0 port on the machine does support USB booting. We encountered some of the machines do not.
Here it takes about 25 secs to boot Clonezilla live on a USB 3.0 flash drive. I tested on Lenovo laptop X220.
