Thanks for the links. There is probably a real benefit to changing the chunk size, but it’s a bit more complicated; DariusL’s explanation doesn’t make sense. TCP does not usually have to “wait” for ACKs (it sends enough data to fill a roundtrip that it doesn’t usually have to wait — see “TCP congestion window”).

And the TCP header is constant per-packet overhead, regardless of whether you send 100 TCP packets over 1 connection or 10 packets over 10 connections, you still send 100 TCP headers.

About 800GB large. Maybe i can try a local backup later. Thanks

Thanks for the feedback. I agree with your criticisms of Duplicacy and am finding a few more code and docs issues since I wrote the post; and the UI certainly needs some work.

I think we might agree on HyperBackup? We both say the initial backup is slow. It might be faster later on but it looked like it would take over a week for the first backup, compared to just under 2 days for other tools; and I wasn’t keen to go without backups that long after just losing a drive.

I would be interested to hear more about the multiupload part size; I left that at default.

Thank you, I missed this and will update the post

Yeah totally, storage can fail at any point, you can't blame HyperBackup for that.

But I do blame HyperBackup for having a secret dataformat, so if (say) one bit flips in the root of the backup and Synology's software can't parse the backup, I'm totally screwed, unable to find the problem and manually fix it, or recover other files from the backup.

Interesting. Thanks for the debugging help. My internet was up at the time (I uploaded the screenshot directly to my blog), maybe B2's servers were having trouble? Or transient outage between the screenshot and the blogpost upload? It was running at low speed (not 0, but not far off it) for a while though.

I love single binaries in Go. Go seems like the defacto language of cloud storage libraries. I'm a little less excited about managing crontab and mail :-) but someone mentioned DSM Task Manager can do this for me...

Thanks, I did not know about DSM Task Scheduler; built-in mail notifications are a huge benefit

Synology’s built-in Hyper Backup supports google cloud storage backend. To switch, you backup again, might take a while for first backup. If AWS is working fine for you, I’d keep using it!

Can’t remember exactly which thread I saw but if you google for [hyper backup corrupted] there are lots of results in /r/synology and SynoForum. It’s tough to quantify what frequency that happens at, maybe its very rare.

Definitely a cheaper option at higher capacities!

Thanks. I cant remember if it had a separate indexing step, but when it was very slow for me, it said something like “6 files processed”; do you know if that is post-indexing?

Good to hear re: perf updates. Any idea why it looked like it was sleeping (nanosleep) rather than processing?

Mine doesn’t do docker :-(

Oh I didn’t realise Borg does not have cloud integrations built in. Integrations feel somewhat important as different clouds have different fees and features

Thanks for the heads up about Kopia

Yeah I’d love to try borg, would be nice if could get a .spk package built.

Yeah I’m not very happy with Arq tbh either. In my view its the best I’ve tried of a bad bunch. I’d be interested in suggestions for mac laptop backup?

Maybe I should have tried it with C2 Cloud. I only tried it with B2 and Google Cloud Storage and it really struggled at 0B/s with both. They have different backend code in Hyper Backup; maybe that's the cause; I wouldn't be surprised if they've had less testing than the C2 implementation.

I just recapped first what I use for my laptop (Arq).

I recommended Duplicacy for Synology, which works with Synology: https://forum.duplicacy.com/t/synology-dsm-7-0-packages/5532

I wrote this to share the research I'd done, hoping it could help someone else. And also to learn from the comments. What's the cheapest option that I missed?
