Yes it has a version for Linux. Available For RHEL 4 and SLES 9 and 10. The link is: http://www.symantec.com/enterprise/theme.jsp?themeid=sfbasic The limitation of the freeware is: * Maximum of 4 volumes or 4 mount points. Excluding the root FS if you want to encapsulate it. IMHO, if your are new to the Veritas world, general case is don't encapsulate. Too many things to shoot your foot. * Maximum of 2 physical CPU. This freeware is also available for Solaris, AIX, and even windows (sans the VXFS. Not a big thing, just use NTFS.). If you go beyond the limit, it will ask you a warning message. The good thing is if you want support, Veritas/Symantec will give you a license key and it will convert/unlock your VSF to the real deal. > > This is a valid solution too, but was hesitant to say it unless your a > > unix admin. > > What exactly are you referring to as "a valid solution" here.. Veritas Volume Manager (VXVM). A well known and solid product on the UNIX world. It's not heard much on the linux world, that's why i did not say anything about it. The beauty of VXVM is it can be done not only in your domino server, but any live application. Be it Weblogic, postfix, apache, etc. Again, because VXVM operates on the block level rather than the FS level. Another thing, just because it has Veritas File System (VXFS), does not mean you have to use it. It works perfectly if you have want VXVM+ext3 or any FS for linux. You have two solutions here. Either: * 3 way volume mirroring. "poor mans" backup. The 1st and 2nd is for production use and the 3rd mirror is for backup. Detach the 3rd mirror, mount the volume, and backup. When done, attach back and the 3rd mirror then synchronizes back to the 1st and 2nd mirrors. The whole operation can be automated by scripts. I'm really oversimplifying things. The 1st/2nd/3rd mirrors are not volumes per se, but plexes actually. The advantage is that this will work on any version of VXVM, and has performed well on the IT enterprise market. That's why i mentioned it. * VXVM Snapshots. Akin to LVM snapshots. This creates another wo(write only) mirror which synchronizes with your existing volume using available disk space of your disk group. This is much easier and you only have to use a few commands to accomplish this. the wo volume then can then be backed up while your application is humming on the original volume. Preferred way is to use VXVM snapshots. > > It has a steep learning curve, has much better features and > > administration is a pleasure to use compared to LVM... except maybe > > ZFS. > > Hmm I like that Can't resist plugging the awesome ZFS. For snapshots, how about one command to do that? or retrieve the file aa.c or /etc/hosts version few days ago without backup?
