Backup Central

We just upgraded our backup machine and are using an external USB3 hard
drive for backups.

Last night, something went wrong, and when I got in this morning I saw
the following errors on the backup machine:

[88921.670598] usb 1-1: device not accepting address 0, error -71
[88921.670665] hub 1-0:1.0: cannot disable port 1 (err = -32)
[88921.674631] usb 1-1: Device not responding to set address.
[88921.880971] usb 1-1: Device not responding to set address.

Could this be caused by BackupPC? When I unplugged and replugged the
USB hard drive, it started working, but I'm worried that BackupPC is
corrupting the drive somehow.

USB has some "features" built in like randomly disconnecting and reconnecting
devices. What is merely an annoyance with keyboards and mice not reacting for
a short moment, gets more awkward with disks disappearing (and thus
unmounting) and reappearing without remounting...
Needless to say that the feature of "reappearing" is optional and missing in
the most crucial use-cases.

Even when USB3 finally has a speed usable for transfering files bigger the a few
KB in an acceptable time, I wouldn't use for anything of importance. Use esata
when you need something external. Or use drive-bays for hot-swap when you need
to carry around the disks. Of course using a nas-device is also always an
option.

Have fun,

Arnold

hi,

I see that issue all the time with external usb disks and they are not
being used by BackupPC.
Never done much about it except if it kept happening notified the end
user that their external disk maybe dieing.

What????? Why in the world would you think BackupPC which is really
just a fancy perl script be responsible for hardware/driver problems?
Even if BackupPC were responsible, you give absolutely no information other
than a hardware error to help anyone troubleshoot your problem.

Just because you run backups on that drive doesn't mean that backuppc
is the cause of your problems. I mean, you probably have hundreds if
not thousands of programs on your system. Do you ask the same question
about every program on your system on the random chance that one of
those programs might be causing some totally unrelated hardware/driver
error?

The only even remotely possible connection with BackupPC is that
backups are disk intensive so it is possible that BackupPC brings out
instability in your hardware more than say just plugging in the disk
and reading a file or two.

I'm sorry, I'm not trying to insinuate anything negative about BackupPC.
I've never seen this problem before, and it was during a time period
when I was writing a ton of data to the drive through backuppc, so I was
merely checking to see if people had seen this before. I do not even
remotely understand everything that BackupPC does.

Regarding some other responses, I'll be sure to try eSATA next time
instead of USB to see if that tends to be more stable. I could also use
internal drives, I suppose...the real reason we're using external disks
is so that we can replace them and store them off-site every once in a
while. Using a pre-packaged drive was simply more convenient.

Thank you guys for your help.

You can get internal trayless hot-swap SATA bays that work pretty
well. If the drive is 750G or smaller you can even do it with the
more convenient 2.5" drives. The WD scorpio black series is notably
faster than the blue version - both need a partition allignment that
works with 4k sectors, though. Someone might even have a 1TB 2.5 "
drive in the standard height by now.

I use one of these external usb/eSATA -> SATA docks, they are about £20
in the UK and let you hot swap a SATA drive a bit like a tape.

We use docks similar to these for our backuppc offline copies, they are
very handy indeed.

I highly recommend **against** using any protocol conversion in the
mix "USB to eSATA" or whatever.

True eSATA is fine - obviously the quality of the hardware is an
issue. Firewire is also OK but getting rarer these days.

Internal SATA to eSATA should also not be a problem, not really doing
any conversion there.

Opening drive bays are really cheap and easy, just protect the drive
well for transport.

There are also eSATA "docking stations" that take a bare drive
standing up on the desktop.

Careful about hot swapping, all the hardware in the chain, as well as
the drivers on the OS need to support it, and obviously make sure
nothing's accessing the drive and dismount first.


Unless your data isn't important, then do whatever you like. . .
