We have a server with 2x32gb sas raid 1 and 4x1tb raid 10 + 2x1tb hot spares. Whenever we try to copy the 1tb and 1.5e6 files to a backup location (even just using tty1 cp command) it fails.
We have tried using backintime and dejadup, and resorted to a manual cp to an external usb2 HDD. When that failed, we tried installing an internal HDD on the mobo (not on raid) and another cp, which also fails.
The failures lock up the system and we are left with an unfortunate hard reboot situation. After reboot, syslog tends to be empty (only containing newly booted data) and we haven't a clue where to start.
It has been 3 weeks since our last successful backup and we are getting nervous...
-using 3ware raid controller, 8gb ram and nvidia pciexpress graphics with a gigabyte mobo and xeon 4-core processor.
Output from dmesg:
dmesg output full
Output from kern.log:
kern.log output full
Sorry - I didn't get very far into the post you linked and decided I pretty much know how to direct stdout to a file. Of course, I missed the important bit about pastebinit. hhhh... n00bs...
We have successfully completed a full backup over the network via SAMBA on both Ubuntu 10.04 and Windows 7 Pro systems without a crash. It is slow, but it completes.
