I use a 4 step process to regularly backup all presets.
1. Backup using fractal bot. This gives you bank, ir and global files. The bank files are bulk dumps of the banks.
2. Preset exports. In Manage Presets right click, highlight all and export all presets to a dedicated folder. This gives you the granularity of having all separate presets ready at any time.
3. Export cabs. Similarly, in Manage cabs, I right click and export all cabs to a folder. This gives each ir as a separate syx file.
4. I use fractool and export a csv file that maps every cab to their preset. This also helps me in finding if duplicate irs in the user ir bank exist and to see which irs are not used for presets. (In case I need to free up slots)
This covers everything. You could also export bundles for your most used presets. I still wish there was a bulk way to do this.
However with item 4 above it is covered off.
After all this you have everything you need in case issues arise and if you have to revert to a previous firmware.
