Windows: C:\ProgramData\Backblaze\bzdata/bzlogs/bztransmit/bztransmit08.log Macintosh: /Library/Backblaze.bzpkg/bzdata/bzlogs/bztransmit/bztransmit08.log These are in plain text and mostly readable, and found here: It might be super interesting to see your logs. I have the ideal situation (less than 5 ms latency to the Backblaze datacenter from my office) and I can backup 400 GBytes in maybe 4 hours? "B2" was created last, so it is a little better thought through and returns JSON (more hip) instead of XML (older, but still pretty much the same thing), but that honestly shouldn't affect ANYTHING.Īround 400 GBytes to back up. I'm curious where you are physically located (in relation to the Backblaze datacenters in California and Arizona)?īoth "Backblaze Personal Backup" and "Backblaze B2" push to the identical pods and vaults, through extremely similar APIs. I wouldn't expect them to be any different. More troubleshooting to do, ut that's where things are pointing now.ĭisclaimer: I work at Backblaze and wrote a lot of the upload code on the Backblaze Personal Backup client. UPDATE: Pretty sure this issue is something on my network and not related to Backblaze. CloudBerry practically maxes out my connection. What's the logic behind this? Is the B2 pipe just that much faster than B1? Or is the Backblaze Personal Backup client to blame (processes used for de-duping, chunking, etc.)? I don't think I've seen greater than 20 Mbps with the Backblaze client at any point during the backup. For the most part, it's been set to 30 threads, which I've found the best throughput with. Bandwidth limiter is off and I've experimented with the thread count. which will be around 460 GB in this case.Ī week later, I still have over 200 GB remaining in the initial backup. This data was backed-up in less than 24 hours using CloudBerry Backup with 3 separate backup jobs, each backup of specific data.Īs a test, I then installed the Backblaze Personal Backup client back on this same computer and started a new initial backup. I decided to go with B2 on one computer (around 400 GB to back up). I currently have a fiber connection with 1 GB up/down, no caps. I don't recall how long the initial backups took, but there would have been less data then - as well as a slower internet connection.
I've been using Personal Backup on 3 computers for years. Why is Backblaze Personal Backup exponentially slower than backing up to B2?
