Hi Michael, As you mentioned, the community originally planned to remove support for creating new "snapshot-based" backups in 9.0. But, luckily for your case: it fell off my radar and was never actually removed. So you should still be able to create snapshot backups using the incremental=false flag (i.e. /solr/admin/collections?action=BACKUP&incremental=false), even in Solr 9.0.
Officially, the functionality is deprecated, so it shouldn't be relied on going forward. But it is still technically there if you want to use it.
