Failing to copy files to network volumes

[Bob Zelin]

I use 10.8.2 server for all new systems. I have NOT seen this problem, but I have seen corrupt data transfers of large volumes with OS X Lion, so I appreciate the link, and I will check out Integrity Checker from DigiLloyd.

good post Eric !

One thing that concerned me initially was running LTO tape writes directly off SAN volumes. but BRU PE does a verification pass, so I’m a little less stressed. but not much.

I have not relied on the Finder for many releases (10.7, 10.6, 10.5, 10.4, and earlier). I’m sure we’ve all experienced failed copies for one reason or another and lost much time chasing down directories to see where the Finder decided to leave off…a major pain.

I recommend to all my customers NOT to rely on the Finder for copying critical data…purely because there is no verification or sensible logging. Who of us has time to literally check every single file’s integrity, especially when copying hundreds of GBs to dozens of TBs of data?

There are a number of software tools for the Mac which offer data verification, and while this step can literally double the transfer time, at least you can sleep at night. Some of these tools also offer logging, showing you specifically which files may have issues. These tools have also helped suss out issues with RAIDs and other physical media issues based on verification failures.

My favorite on the Mac platform is ChronoSync, which I’ve been using and recommending for years.
