I am making a "restore" disc for a family member's laptop that I freshly installed Windows.
The "backup to another location" veeam backup filesize is 22 GB
hopefully BD-R XL 100GB 'm disc' media supports very large file sizes

I have a couple of blank BD-R XL discs to test, I conceed I might make a few $10 coasters the first time I do this... hopefully your advice can reduce the number of expensive coasters I create *wink*

facinating.... fresh install backup size = 6 GB, with browsers installed + fully compliant with all Microsoft updates the backup size ballooned to over 20 TB sheeh!
(yes before taking an image I did a "disk clean up" w/ every possible additional setting)
=======
My fall back option is use veeam media creation tool to create a USB bootable drive to combine with the bluray that I will write the veeam backup files to.
althought I would prefer to give my family member the bootable bluray disc by itself (one less thing for them to manage)
Thank you in advance to everyone who responds helping me with my question!
