Hello! I've read some other posts about backup software posted here and i thought i'd ask a more specific question i haven't seen asked that i feel might be helpful to others who share my specific setup.

my setup: I have proxmox backed up with proxmox backup server. super wonderful. but i also have hosted a ceph share that connects everything together. one ceph is for VMs and thats already backed up and all, but i have a second ceph to store media, game server data, minecraft server data, file backups, etc... basically a massive drive of just loose files.

since i'm really happy with proxmox backups and have my vms/lxcs under control, i'm only worried about this big massive share of "just files" i need to back up. i've been using restic but need an webgui to be able to perform prescise restores of specific folders or specific files.. and i have terrabytes of data there that backs up nightly. resticwebui glitches constantly and i've seen restic not be 100% trustworthy on some very very large files, so i'm willing to switch completely to a different system which makes this question so much more easier to answer. i'm not looking to back up a PC or a VM or something. litterally just nightly backups of a massive share (mounted as a folder already so dosn't need any special support) just able to back up a massive size of data and allow me to have a working webGUI with the ability to restore specific things.

​

does a tool like that exist? just something i can set up easy, backs up a massive folder, to a local harddrive store i've already got set up, and then allow me to do specific restores whenever. kudos if it supports OIDC or SAML, since thats what i've been using as SSO for my home servers but the only thing that matters is specific restores and the fact that it doesn't take up all of my ram like restic does
