rsync problem

[smallgod]

I am using the latest Raspian image and rsync 3.0.9.
I was having some problems with ssh dropping out but I think I have that fixed by setting ssh TCPKeepalive to no.

When I try to backup / using:

Code: Select all

rsync -av --progress / backup machine:/backupfolder/ (from the Pi)

OR

Code: Select all

rsync -av --progress /backupfolder/ PiAddress:/ (from the backup machine)

the backup chugs along until it reaches the same files and then I get a broken pipe.

When I get to the files (I guess they're not normal files) in:
/sys/devices/platform/bcm2708_usb/
I start to get errors and then the transfer quits, I cant get any connection over ethernet after that and need to reboot the Pi.

I can get the same result right away by trying to backup the /sys/devices/platform/bcm2708_usb/ directory.

Here are the errors right before the transfer stops:

spramdump
Write failed: Broken pipe

[ksangeelee]

The directories /sys, /proc, /dev are special filesystems, and they shouldn't be included in your backup (as you discovered with your crashed machine).

If you use the -x flag in rsync, then it will limit the backup to a single filesystem ('/' - your root filesystem), which means you may need to run rsync a second time, this time for the /boot filesystem (since it's on a separate partition).

There's also the --exclude option, which allows you to list paths to exclude. There may be other ways.

[bleistik]

Nonetheless, the OS shouldn't crash.
You can reproduce it by doing:

cat /sys/devices/platform/bcm2708_usb/spramdump
which results in the following on the console.
