Snebu VS corectrl

As such, I use tar for the serialization of backup data for Snebu (https://www.snebu.com), which has a plugin (tarcrypt) that operates on the data streams. Snebu ingests tar format, and emits tar format, so all you need to backup/restore a host is ssh access (server can pull backups, or client can push backups). So tarcrypt was added as way to do client-side encryption, but still be able to to submit recognizable tar files to Snebu's backend (which indexes, de-duplicates, and snapshots backups).

Snebu, on github. Simple Network Encrypting Backup Utility.

Details are at https://www.snebu.com/tarcrypt.html if you want to look it over (and tarcypt is part of the Snebu project https://github.com/derekp7/snebu). I'd love to get another pair of eyes on this to point out any non-obvious security limitations.

Since I've had a handful of users ask about cloud storage for Snebu, Would you be interested in adding Snebu as a supported protocol? It should be similar to how you currently support Borg. For Snebu, the client runs find and tar, sending results via ssh to the snebu binary on the remote host. And more recently client-side public key encryption support has been added via a client-side filter called "tarcrypt". Ideally, a customer would use Snebu to back up to a local device on their network (for example a Raspberry Pi with a large USB drive attached), and then use Snebu's efficient replication to send deltas to the cloud-hosted server. Client files are stored individually (deduplicated) on the Snebu server, and metadata is in an SQLite DB (advantages over Borg is more open standards for the data storage and public-key encryption, disadvantage is file-level instead of block-level deduplication and a project that isn't as widely used).

If you are interested, I would be more then happy to have an extended discussion with you going over implementation options, and updating the client side script to make it work better with your service. (https://www.snebu.com, https://github.com/derekp7/snebu, and the tarcrypt extensions to tar are described at https://www.snebu.com/tarcrypt.html).

Would a mention of my open source backup system, Snebu (or https://github.com/derekp7/snebu) fit in this thread? Elevator pitch -- GPLv3 C code, snapshot-based, compresses, encrypts, deduplicates, can back up clients without installing an agent (just need ssh, bash, tar, and find commands on client for "pull" backups), push backups can have restricted permissions (i.e., give a client permission to push backups only, but not delete backups, or give a user restore-only permissions). Uses tar to collect the data, stores metadata in an SQLite DB on the server, files are stored in LZO format (can be read directly with lzop) (unless client-side encryption is used, but the data can still be decrypted with openssl then decompressed with lzop). Encryption is public-key based instead of needing to keep a shared symmetric key or passphrase laying around on your backup server.

I created and use Snebu -- I'm working on getting it submitted to Fedora (waiting on package review now), doing daily snapshots of my fleet to a raspberry pi with external 12 TB WD Easystore drive. Provides push or pull based backups, granular access permissions, client-side public key encryption (RSA + AES-256) with HMAC validation, server-based data catalog housed in SQLite, multiple client support, global (cross client) file-level deduplication and compression. Works great for backing up a large range of OS versions since the client-side doesn't need an agent -- just bash, tar, find, and ssh.

Have you tried CoreCtrl [0]?

I have a 7900XTX and performance under Linux has been at least on par with Windows, sometimes better (though not by much).

> May i ask what driver features are you missing?

I'm not GP but I'd love to see frame gen and stuff like anti-lag and upscaling integrated into amdgpu with some sort of official way of setting it (though looking at Adrenaline it might actually be best if it's left up to the community to create the GUIs).

Basically the 7800 xt has this bug where I need to lower the core clock of -80mhz to avoid it crashing with 2 different hdmi/vga monitors or something. On windows no problems, but what about arch linux? How do I lower it? Looks like corectrl doesn´t support 7000 series gpus (from what I understood), please help yall!

sudo grub-mkconfig -o /boot/grub/grub.cfg Reboot your system. You should have more controls when you select Advanced as Performance mode. https://gitlab.com/corectrl/corectrl/-/wikis/Setup

> The AMD experience on Linux is vastly better than the Nvidia one.

I just wish we had an equivalent of AMD Software on Linux, so I could mess around with the settings more.

For example, I like to limit the GPU to 50-75% of it's total power for ambient heat/cooling reasons, or UPS/PSU/electricity bill reasons when specific games make it hard to cap framerates.

With AMD Software on Windows, it's no big deal. On Linux, the best I found was CoreCtrl: https://gitlab.com/corectrl/corectrl

Sadly, it doesn't seem to work all that well for my use case, which I mentioned in my blog post when using Linux instead of Windows as my daily driver at home too: https://blog.kronis.dev/articles/a-week-of-linux-instead-of-...

> You see, by default the card controls its own GPU and memory clock values, which means that when idle the GPU draws around 40 W of power. However, if I want to set a limit for how much W in total it can use, it also makes me set the GPU and memory clock values, which will them be fixed: so at idle the GPU will use about 60 W of power.

If you set it to POWER_SAVING instead of 3D_FULL_SCREEN, it uses the highest boost clock a lot less. Or if you use something like corectrl's application profiles (maybe the Windows vendor driver control panel has them?), you can selectively disable boost clock states in specific games.

I'm bias toward Asus motherboards. I have an "Asus TUF GAMING B550-PLUS WIFI II" and a "Asus ROG Crosshair VIII Hero (WI-FI) ATX". Both boards have a fan control feature in the BIOS/EFI. On the Windows side both boards come with Ai Suite 3 software. On the Linux side you might want to take a look at Corectrl ==> https://gitlab.com/corectrl/corectrl

I think CoreCtrl might offer some of what you're looking for.
