Files fail to come online when connecting to file system archives using SMB on Mac OS X 10.6.7, 10.6.8 and 10.7
A change Apple introduced starting with Mac OS X 10.6.7 has led to questions about file system archiving support for Macs. The bug was finally fixed in Mac OS X 10.8.2. This article explains the options for previous version of Mac OS X.
What changed in Mac OS X 10.6.7?
Apple made a change in the Mac OS X 10.6.7 update that prevents Macs from using the SMB/CIFS network protocol to recall files that are stored offline with a file system archiving solution. The problem remains in 10.6.8 and 10.7.x Lion.
Is it still possible to use file system archiving from Macs?
Yes if a Mac uses Apple’s native AFP network protocol to connect to the server, instead of the Windows SMB protocol, recalls will continue to work properly.
How can I use AFP with a Windows server?
The AFP protocol can be easily supported on a Windows 2003 or 2008 server by using GroupLogic’s ExtremeZ-IP software on the server. A trial version of ExtremeZ-IP is available on GroupLogic’s web site. Using AFP also offers many other compatibility and performance advantages for Macs.
Do I still need ArchiveConnect?
Yes, if you have Macs accessing file system archiving solutions. ArchiveConnect is designed to allows Macs to browse archived files without triggering unintended mass recalls of offline files. A Mac running ArchiveConnect will work properly if the AFP protocol is used, regardless of the OS X version. However, please note that a Mac using an SMB connection with 10.6.7 or later will not recall files, whether intentional or not, with or without ArchiveConnect. A trial version of ArchiveConnect is available on GroupLogic’s web site.
Will the Mac bug be fixed?
We reported the bug to Apple as Bug ID # 10836961 and it was fixed in Mac OS X 10.8.2.
Where do I go from here?
We recommend that organizations using Macs with file system archiving use ExtremeZ-IP and ArchiveConnect together to give Macs the benefit of AFP along with user-initiated file recalls that work as expected.
