The crypto in Borg is bad. Even has its own page in the docs about how bad it really is. The tl;dr is "there is one AES key per repository and we use this with AES-CTR and trust the remote server to not fiddle with the counter". https://borgbackup.readthedocs.io/en/stable/internals/securi... Last time I checked there was still no work being done on improving performance. Multithreading has been on the agenda for year…

Like many open source projects, Borg is low on developers. The two points you mention are both known and on the agenda for this year. Since you seem to have experience with crypto, why not add a PR? It's all in Python and fairly readable.

Borg isn't really low on developers, it has high churn, i.e. repels developers.

Is it weird that I don't have GBs of my own personal files/data? I get if you have movies/tv shows or whatever, that's different. I just don't know what personal data you could possibly have that would amount to GBs...

Photos and videos. All My email. I as a musician have about 40 gigabytes of personal recordings that I have used for auditions and pre selection rounds in competitions. All in all it is about 800gb and growing.

Since my son was born the amount of photos and shitty quality videos that I backup is staggering.

Ah okay, fair enough! Guess I just don't really have that much personal data but it makes sense in your situation.

I just don't understand rolling your own backup drives in 2018 unless you're up to something nefarious. I rest peacefully knowing my data will never be lost by Dropbox, and the immediate backup means I don't have to mess with slow, periodic all-at-once backups.

> I rest peacefully knowing my data will never be lost by Dropbox This is still putting all of your eggs in one basket. What happens if I lose access to my account?

It's two baskets - dropbox and local.

Do you ever worry about the Li-Ion pack having issues in the hot car?

I've never specifically used a Li-Ion pack in my car PC setup, storing it in the heat would worry me a bit, but surprisingly, operational temps in a car aren't bad: If he's using it after he drives it, the car has likely been cooled or heated for driver comfort, and it'll take time after he parks for the temperature in the car to return to "outdoor" levels.

My bigger concern is just storing it. It sounds like he’s using just a regular powerbank type battery which is li-ion. Letting it sit in a parking lot for a day in the summer then turning it on probably isn’t a very good thermal situation. I wonder if some sort of sealed lead acid might be better. Far more inconvenient for power management though as some sort of circuit would have to be created.

The best solution I found as an alternative to an off-site copy is to set up a USB drive and something like a Raspberry Pi in my car. When I pull into the garage, the house server senses it and syncs new data to it. This can be supplemented further by having it auto sync to a computer in your office whenever you pull into work. Add in some monitoring so you can get a phone alert if any of the synced copies are more t…

When I had my new 'Man Shed' (It's a large workshop really[1]) built at the end of my garden, I ensured I could extend my network to it. I have an old NAS with a couple of large drives in it, and I have scheduled backups that write to it from the main file server in the house. It's not perfect, but it's way better than not having any offsite backups at all. I have a deep distrust of Cloud storage services so for me I…

Distrust in cloud storage in which way? What are yafraid will happen. Which data are you afraid is going to end up in whose hands?

The data I really care about is encrypted right on my laptop,and I backup that encrypted data.

Anyone knows an open source Backup Client that runs on Windows and that support SFTP?

My first thought is "why don't you keep a backup?" I really don't know what the moral of this story is beyond "don't keep one copy of all your data, especially in the same physical location."

Online storage is cheap. Bandwidth is cheap. There's a multitude of solutions in the comments if a consumer solution like Dropbox or Google Drive isn't good enough for you.

As a parent you go through a period of time - when your kid is young - that you take photos and videos of EVERYTHING that they do. Its silly now that i look back. Certainly it is important to capture moments, but to over-document everything is silly...now i take minimal photos/videos, and just be present in the moment. Oh, and my data accumulation has precipitously gone down since i've mellowed out. But, yeah family photos/videos adds up like crazy.

Does the RaspberryPi have enough CPU for disk encryption?

I am trying to find cheaper device between NUC and Pi. Lot fewer choices are available. NUC is expensive. I wonder when will 8core ARM based NUC will arrive in the market. No idea is NUC can be powered by Xiomi Mi 2i powerbank but a Raspberry Pi can be Priorities: 1. Gigabyte ethernet 2. Small form factor NUC or smaller. 3. 8+ cores 4. Very low power consumption

There's the Intel Up board. 4 Atom cores, gigabit ethernet, 2xUSB3, 2xUSB2, HDMI and the same form factor as a Pi. You can get expansion boards that break out more USB ports (not on a hub, independent bandwidth), native UART and I2C. I've been playing with them for onboard computing on a drone, so far it is working really well. Price is about $100 for the low spec ones.
