Sparsebundle zero bytes on disk
DaveYHZ
though it is attached to a droboshare. The issue now is one of my
macs (macbook pro) is no longer backing up. The other, iMac is fine.
When I try to "Backup Now..." TimeMachine gives me the error: "Time
Machine could not complete the backup. The backup disk image /Volumes/
DroboCapsule-1/DaveYHZxxx.sparsebundle could not be accessed (error
107)."
If I "Get Info..." on the Volumes/DroboCapsule/DaveYHZxxx.sparsebundle
it shows a size of Zero bytes. :( I'm guessing I've lost the last
few months of Time Machine data then.
Does anyone know what may have caused this data loss and how to
prevent it in the future? Everything from the network switch through
the Drobo is on a UPS so there was no power failure.

Yes, yes.

I have two sparsebundles on there, one for each mac. Each was created
at 1tb - I don't know how big it ~was.

So what is better than TimeMachine? I take biweekly snapshots using
SuperDuper for full machine restore. I've got Mozy doing backups
too. My TimeCapsule killed my backups too many times to bother
complaining about. I was hoping Drobo would be better. Looks like
it's time to investigate the Windows Home Servers :S

How is the computer for that backup attached to the network? Wireless
or Hardline?
Does the Droboshare in this case have the "Add swap Memory" module loaded?
The "silly" question: Are the USB, network, and power cables all
secure? The first short USB cable that I received was defective, so
that is an possibility, though one you'd have likely noticed before.

Quickbooks files on SMB shares when a few coworkers "forgot" to turn
off the wifi when plugged in at work. (several headaches ensued).
Quickbooks is flaky even under the best conditions though, so it is
not directly representative.
In theory, TM sparsebundles should not have this issue, but without
logs to prove otherwise... hard to say IMO.
It would not explain the Drobo going to sleep with just the orange
standby light on. Agree this sounds like something puked.
Have you run Disk Utility/fsck.ext3 on the drive after the incident to
see if they could detect any errors?

iMac's bundle is fine.
These are the DroboApps I currently have installed:
# Add Swap Memory
# Dropbear SSH
# EtherWake Wake-On-LAN
# Jumbo Frames
# netatalk
All of the cables are secure.
Why do you ask about the Swap Memory?

plays russian roulette with processes, and picks one to kill. If that
happened, the overall effects are not easily predictable. It could
have been an explanation for the orange sleep and possibly the
corruption as well, if a critical process was stopped. However with
swap enabled, performance would drop if it was used, but it shouldnt
die.
