I have a full version of Acronis (and not even a recent version of it, but do research acronis version vs Windows OS version support) so I haven't really investigated what the limitations are for the versions that come with hardware like SSDs, but generalizing...
The full version lets you make a recovery loader on your OS boot drive with a boot menu (defaulting to loading windows if you don't...) hit a key during boot to load it, to recover from the drives it sees, including HDD, SSD, optical, USB, etc, whatever the bios presents as a storage volume.
It also lets you make a bootable USB flash drive so you don't "need" that, which you could put the restoration image files on, or once the recovery program loads off the flash drive, browse to where it is stored, again based on what the bios presents as storage volumes.
In a minimalist configuration for a windows client, I'd partition the single SSD into two partitions, make a backup of the OS and apps partition onto the 2nd partition, and then in case the SSD failed, use acronis to make a bootable USB flash drive (and of course, test that the target system can BOOT from it to load acronis or else that is pointless), and copy the partition backup files that Acronis wrote to the 2nd partition, to the USB flash drive. The 2nd SSD partition is not necessary, Acronis could just save the partition image backup files straight to a USB flash drive or a network shared volume instead, or external USB HDD, etc.
In cases where the systems need a FAT32 formatted USB flash drive to boot from it, I have acronis make the partition backups broken into multiple 3.9GB files to overcome the fat32 4GB file size limit.
I suppose I went off on this acronis tangent because if your optical discs have the backup file formats I'm used to seeing, like filenames of *.tib, and then if broken into smaller files for fat32, subsequent files in the same backup would be *(n).tib format, those could be copied off a CD rescue disk onto a USB bootable Acronis restoration flash drive if you have a version capable of making the USB bootable flash drives... in case your prior backups have some value and you want another way to restore them besides an optical drive... but you still need an optical drive to get them off the disc and moved elsewhere.
