I’m sorry for yet another Time Machine performance thread. I just wanted to make sure I was getting the most performance I could. Sorry for all the info, but I figured it would be better to have to much than not enough. :wink:
I recently purchased the 4TB My Cloud. I immediately upgraded it to the latest firmware, which after reading that some people were happier on earlier firmware, may or may not have been a mistake. My goal is automatic wireless backups of my late 2013 Retina Macbook Pro and my wife’s late 2009 Macbook. She’s backing about 225GB from her internal SSD that I upgraded it to. I need to backup at about 1.5TB total. My internal SSD has around 275 GB and the rest is on a 2TB USB 3.0 WD Passport.
Unfortunately, I didn’t realize that my router didn’t have a gigabit switch until I purchased this. :cry: I understand that it’s going to be painfully slow going that route. For kicks I started out trying to do a backup of everything on mine at once but quicky realized that wasn’t going to work.
Since my wife’s had an ethernet port, I shut down the drive, connected it directly to the laptop, then pulled the plug on the drive and plugged it back in. I was able to backup my wife’s 225GB in 12 ish hours or so, I forget exactly, but I felt it was reasonable.
I’ve had a tougher time with mine, since it has no built in ethernet port. I finally did as some recommended and excluded everything but my documents folder for the first backup, and gradually added more and more until I got my entire internal backed up. Now I’ve moved on to the external, which is two folders, Pictures and the other Videos, both of which are around 550GB or so. I’m currently backing up the Videos folder. I started it around a week ago and completed about 325GB in that time. Yesterday I broke down and bought the Thunderbolt to Gigabit Ethernet adapter in hopes of speeding up the initial backup. Over wifi, I was seeing 3-6 MBs write speeds. With the adapter, I’m seeing around 36 MBs. Much faster, but I just want to ensure that’s the fastest. I know a lot of people have seen Lon’s videos about the drive, and he gets about 46 Mbs in his:

That’s not a lot faster, but another 10 MBs is a lot when you’re trying to eke out every little bit of speed. I know all networks are different, have different overhead, etc., but since this is just the drive connected directly to the laptop via the Cat 5e cable included with the drive, could something be hampering it? I spoke with support last night and they said I should be seeing faster speeds than that, potentially more like 80 MBs write, but that was tested via a Windows 8 machine and using a Cat 6 ethernet cable, and that Macs usually run at the speeds that I’m seeing. They also tried blaming it on the Thunderbolt adapter, but I switched over to my wife’s built-in gigabit ethernet port and saw the same speeds. Would Cat 6 help?
I resumed the Time Machine backup at 10:14pm last night, this time over ethernet. It ran a scan and found 207.33 GB (184.61 plus padding) still needed to be backed up at 10:17pm. As of this morning it had only done 23.22 GB. That sounds more like what I was seeing over wifi. I’ve seen others on here saying they could get around a GB a minute, like at the bottom of this post:
I will probably try his steps tonight when I get home. I was really hoping it would’ve been able to do the 200 GB overnight and be done this morning when I got up, wouldn’t that be a normal expectation over ethernet? Especially since my wife’s had done close to that. Even if it wasn’t done, I figured it would be close, but 23 GB was a shock. :confounded: Again, I know it’s going to be stupid slow over wifi until I upgrade my router. I’m ok with going over ethernet for the times that I’ve added a lot or made a big change. The videos it’s working on now are .m2ts, if that makes a difference, but from what I’ve read, it’s usually faster with fewer big files, than a lot of little files.
Here’s a portion of the log, if it helps:

It finally started hitting around 4-5 GB an hour. Is that normal over ethernet?
Again, sorry for the rehash of the subject, and the long post.
Thanks to everyone in advance, the community seems very helpful!
