I do have both of Curt's books, and have given advice to him regarding some of the website changes that he's made over the years (along with my fellow former CT co-workers), but I must confess that there are a few bits of his site that I may not have seen or may not have seen recently. > However, since you refer to laptops and wireless VPN connections, etc., > I would recommend that you just use the native Windows backup tools to > dump a backup file onto a Samba share on a Unix box that Amanda can > back up normally. I've done that sort of thing with my wife's previous laptop (which is now my FreeBSD server), and the problem is that I don't think that the backup image is readable with the newer tools. I want something that will continue to be readable even after her next OS upgrade, and I don't trust Microsoft to allow me to do that. Are there any other good W2K backup tools that are available (freely or relatively inexpensive) and which are reasonably likely to have good forward compatibility? Legato Networker is not likely to be an option here. > For Mac OS X: someone posted patches this past week to get Amanda > working with gnutar on OS X.

Cool. > At this point, there is only one reason that I might hesitate to > recommend Amanda to anyone with a little Unix experience: Well, I've been doing Unix system administration for fourteen years, but backups (especially with mixed client platforms) is one particular area that I haven't gotten into. You're not going to scare me with the concept of getting Amanda to work on MacOS X, or using Amanda in general -- I've been around too long for that. However, there are some deeper issues that I remain concerned about. > it cannot > span a single backup image over more than one tape. Ahh, yes. That would be a killer. I have a 40GB hard drive in this PowerBook G4, with one partition/filesystem of 15GB and another of 19GB, and I don't know of any reasonably priced tapes that can hold that much data -- I don't trust the Ecrix VXA stuff, because they got bought by Exabyte, who has a vested interest in seeing the technology die in favour of their in-house stuff. > It can use more > than one tape during a backup *run*, but if any of the backups is > larger than the tape the backup will fail.

Especially since I'm just about to really get into editing home video digitally, and I need to dump all the video I've captured (several 80 minute MiniDV tapes) and then start putting all that together. I may need a terabyte of storage or more, but so long as I buy ultra-high capacity and relatively inexpensive drives, I think I can RAID them at the server and still keep the costs within reasonable limits. -- Brad Knowles, <brad.knowles@skynet.be> "They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety." -Benjamin Franklin, Historical Review of Pennsylvania.
