AOMEI First Backup Is Slow
-
I'm now doing my first backup with AOMEI I am backing up these two drives... - Internal Drive C: 77 GB - External Drive M: 316 GB ...onto a single External drive. This thing has been going on for way more than 12 hours now; maybe a full 24 hours by now; I'm not totally sure. The interface between the external drives and the desktop computer is USB, And I think that's 3.0 on the plugs; They both have the "SS" Logo printed next to them. AOMEI Continues to report consistent progress, 83% At this present moment (And I started this yesterday) As best I remember, I killed every other app before I started the backup. I came across [THIS REAL SPEED FAQ](https://www.verbatim.com/UserFiles/File/USB 3 FAQs.pdf) from verbatim, which contained this...
From Verbatim's Website...
Sustained transfer speeds (real life) for external hard drives are about 85MBps for USB 3.0 and about 22MBps for USB 2.0,
I welcome correction on my arithmetic here. Even if I'm getting the 22MBps speed, I calculate between 18,000 and 19,000 seconds of time That gives me something like five or six hours Clearly, I don't have all the facts here. I welcome better brains than mine, who might direct me to something smarter.

I can't tell for sure because I don't use AOMEI but I have experienced a couple of times that sending two different big files to a USB makes it go slower than sending one after another. If AOMEI is backing up both drives "parallely" that could eventually call the same effect. At best wait for @OriginalGriff he is the AOMEI power user here.
M.D.V. ;) If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about? Help me to understand what I'm saying, and I'll explain it better to you Rating helpful answers is nice, but saying thanks can be even nicer.

If you're only getting 20MB per seconds (that's megabytes, not megabits), that's USB2, not USB3. I've been bitten by this multiple times. When copying over USB3, I often get well over 100MB per seconds. If something's not configured right, or I have the wrong port, I *do* see 20MB/s.

Are you using compression? That slows it down a bit. Are you backing up the files to a single backup archive file, or are you backing up each file on its own? If you're doing each file on its own, that will take much longer due to the overhead of the file system having to create each file and the drive having to seek all over the place.
The difficult we do right away... ...the impossible takes slightly longer.

I'd guess that either you have compression set to very high, you are backing up more than you thought, your USB is connecting via USB1, or your destination disks are having problems and you get a lot of retries. I backup 1.8 TB across two disks, using "Normal" compression, "Intelligent sector" on, and USB 2 (though I've just noticed my drives are USB 3 so I may start plugging them into a different port in future). I generally start them around 18:00, and they turn the computer off some time early in the morning - around 03:00 IIRC - that's about what I'd expect for any backup system. I do close pretty much every app that's running before I start so there aren't too many file changes while the backup is in progress. Are you going via a hub or plugged directly into a port? Hubs can be iffy sometimes - especially the cheaper ones, and I know how many devices I have plugged in ATM ... :-D

Compression is "Normal"

Compression is set to normal

Duh. Never thunk it thru that far

Anything's possible, But these are disks ordered straight from Western Digital and I believe this is the first or second time I've ever used them

The final size of the destination file was 313 Gig, I believe

No hubs, directly into a port; on the front, yes, I see them now; both are plugged into the front

My little 400 Gig task apparently took 26 hours; and the first 18 or 20 of those hours were totally hands-off (I was deliberately not present) Thanks for the ideas. Keep them coming.
