r8152 VS dduper

The network adapter performance is underwhelming and it keeps disconnecting every 2-3 min. It is connected in a usb-c port on a Thinkpad T480s. I found a post online from someone having this issue on Ubuntu. I tried adding the udev file rules for Realtek adapters mentionned in his post without success.

Those udev rules came from this file: https://github.com/bb-qq/r8152/blob/master/50-usb-realtek-net.rules (lines 12 and 13, with 8 and 9 subbed in.)

I saw a post from someone recently who used these USB adapters and this driver to add 2.5 Gbe capability to a DS1821+, though it should work with most current Synology devices.

Thanks for the suggestion, I wasn't aware of this option. I have since found this page https://github.com/bb-qq/r8152 and as it's looking like the nic on my NAS is in distress I am looking into ordering a usb type-a CableCreation 2.5G Ethernet to USB Adapter for AU$30

You will need to install additional drivers.

Another way is to get a 2.5gbe usb adapter and plug it into the USB port on the Synology. There's some software on GitHub that will make this work. I opted to go with an official Synology card. I already have a relatively complex network set up. I don't want to chance a sudden incompatibility and lose a weekend trying to figure out what went wrong.

In some cases deduplication happens at the file system layer transparently without you even realizing it. E.g. there are tools like https://github.com/lakshmipathi/dduper

I agree that image editing workflows are a different use case more suited to perceptual hashes than cryptographic hashes.

ddupper uses a patched btrfs command to read file hases from the raw disk. It requires root access and is kind of a hack.

There are various tools to use for COW deduplication, such as bees, duperemove, rmlint, jdupes, and dduper

Hmm, could we use something like dduper to achieve this, if they don't have it included?
