ASR

I am about to backup disc volumes attached to my Xserve, including the boot disc volume. I read this good primer from ADC about command-line backup strategies:

http://developer.apple.com/macosx/backuponmacosx.html

After reading this article, it seems one can not go wrong with ASR. However, the excerpts are worthwhile:

This article does not cover BSD flags, or systems prior to Mac OS v10.4 Tiger. And for simplicity, this article assumes that you have not turned on ACLs (using Mac OS X Server or fsaclctl) on the filesystem you are wanting to back up.

and

It is not enough, in most cases, to duplicate the contents of files; the filesystem hierarchy, permissions, dates, and other metadata must also be preserved.

I am running Mac OS X Server 10.4.6 on my Xserve and a few of my disc volumes have Spotlight indexing enabled so its important to be able to use a backup / restore utility such as ASR that will ensure that Spotlight indexing and metadata (among other other aspects of the filesystem) is preserved. What is interesting, is that Tiger Server by default has its boot disc volume enabled for use with ACLs, as in:

$ fsaclctl -p /Volumes/Server\ HD/
Access control lists are supported on /Volumes/Server HD/.

In my particular instance, I am not *using* ACLs (at least not that I am aware of, I have not consciously enabled them such as with WGM). My other disc volumes do not have ACL support enabled. So what does it mean if the boot volume running 10.4.6 Server, for example, supports ACLs but they are not enabled. Will ASR be able to preserve a snapshot of the boot volume perfectly are do I have to take into consideration that Apple has enabled by default the support of ACLs on the boot disc volumes of Mac OS X Server 10.4.6?

Note: What about BSD flags? I have no clue if Mac OS X Server 10.4.6 makes use of them by default and if should the be considered in backup / restore contexts with ASR being recommended as best practice?

Best regards,

Sergio
