Re: [PLUG] Need help backing up my data

I agree, that is VERY slow. Are you sure it is plugged into a USB3 port? Some HDDs are fast at first, but then slow down after their buffers get full (Shingled magnetic recording ), but even then I would expect 20 - 30 MB/s transfer

Re: [PLUG] Need help backing up my data

Even for a spinning disk that seems really slow, especially if it is rated for USB3.0. I haven’t played with spinning disks in years, but IIRC I was getting 30-40 MB/s writes. This drive sounds similar to yours and is advertised at a max of 220 MB/s. Even half that speed would be quite good.

It may be a cockpit error. The USB drive is brand new, and I assumed formatted to vfat. It turns out it is ntfs. I reformatted the drive to ext4, and I am running benchmarks. Initial results from hdparm (on a different machine - SurfacePro 4 running Ubuntu Timing cache reads: 9598.53 MB/sec

Re: [PLUG] Need help backing up my data

Indeed, that sounds really slow: ( 138GB * 1000MB/GB ) / (26hr * 60min/hr * 60s/min ) = 1.5 MB/s ~ 12 Mbps That's in the USB1.x range. If you use USB3.0 and can get 100MB/s write speed, you'd be done in about 6 hours. Have a look at hdparm to get some info on read/write performance of your

Are you using a USB3 drive and a USB3 port, the speed of the interface is what I would think of first. On Fri, Jul 15, 2022 at 8:41 AM Mark Phillips wrote: > I have an Ubuntu 18.04 system with two drives in an lvm with one logical > root partition. I am trying to back up the contents of the

[PLUG] Need help backing up my data

I have an Ubuntu 18.04 system with two drives in an lvm with one logical root partition. I am trying to back up the contents of the drives (ie /) to an external usb drive using rsync. It is taking a really long time. After 26 hours of continuous operation I have only transferred 138 GB out of 2+
