![]() ![]() Setting dedup to "minimal" in the front end appears to have no effect, but if you go in and edit the xml file and tell it to skip the dedup check on all files larger than one byte (essentially disabling it), the uploads should speed up significantly. This is especially the case for me, running crashplan on a low power server XEON clocked only at 2.26Ghz. that actually have decent upstream bandwidth, the dedup algorithm your CPU will be the bottleneck long before your upstream bandwidth is (it's only single threaded, so one core will be maxed). Problem is deduplication algorithms are VERY CPU intense, and if you are one of the few home users in the U.S. The crashplan software assumes that your upstream connection is very slow, and your CPU is very fast, and in that scenario aggressive deduplication makes a lot of sense, as with a very slow connection, every file you don't need to upload saves A LOT of time. I have disabled deduplication in the frontend.Īny thoughts, is this expected? Would throwing more cores at it have any effect?ĭid you ever manually edit the config file to effectively disable deduplication as posted above? Once core seems maxed out at 100%, the other core is hovering at about 20%. I told the client it can use 100% of the CPU, wheter idle or not. I ahve assigned it two cores of my 12 core (24 logical) low power Xeon system. Is this just the way things are with Crashplan, or is it possibly Verizon is throttling me?Ĭould it be a local machine performance issue?īackups are occurring from within a Ubuntu Server guest on my ESXi server. This is obviously a little disappointing. My uploads started at ~85Mbps, but quickly dropped off, and now are averaging between 20 and 30 Mbps depending on when I check. I set my in app upload limit to 125Mbit (to make sure I had a little upstream bandwidth left for other things). For those of you who use Crashplan for your backup needs, I wanted to check what kind of speeds you are seeing, to see if my own install is performing as expected.
