Hi, i will build a little Server with XEN with a Windows Home Server Domain. I will use a Hotswap HDD in a "Wechselrahmen" (i don''t know the exact english translation, maybe "exchange frame") for Backup. And i don''t know how i should do this ... any suggestions ? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

If yes, you should be able to use "xm block-attach" and "xm block-detach" with GPLPV to attach-detach the disk without having to reboot domU (well, you may need to reboot Windows the first time it''s attached). -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
yes it''s a removeable Hard Disk, but without the external power plug like eSata or USB. The Secound Problem ist, what would be the best backup methode for System Partition ?

The English word for the hard drive scenario you describe is most likely "mobile rack" though this may also be a marketing term specific to some brands. Another more generic option might be "internal enclosure" though I am not 100% certain that is accurate. Regarding both terms, I am assuming you are talking about a half-height (one slot) 5.25 inch drive bay device that can have 1 3.5 inch hard disk installed in it (or perhaps 4 2.5 inch drives). If you are referring to a three 5.25 inch slot device that takes 4-5 drives, then I cannot sure on the terminology. All of that having been said, regarding a backup method, the best method would be to backup from within Windows. A third party software might make this easier, but ntbackup (assuming you are running a version of Windows that has this) can make an effective complete backup (be sure you are familiar with how to restore from it in the event of a domU destroying disaster). This is only true if you need the domU to be running during the backup, if you are willing to shut down the DomU to make the backup, I believe you can find a blocksync script somewhere on the internet that might very quickly image the entire Windows partition (after the first backup, which would effectively be the same as using dd to copy the entire partition). If you can do something like this, you wouldn''t need to attach and detach the drive to the domU as explained by Fajar.

yes, mobile rack seems to be the right word :) I only want to use one, for the backup Hard Disk, that the backup is not in the same room, when there is a burglary, fire or something else. I think i will try the external backup with dd and decide it after first testruns and the needed time Am 22.02.2010 15:03, schrieb Dustin Henning:> The English word for the hard drive scenario you describe is most > likely "mobile rack" though this may also be a marketing term specific to > some brands.

You may also search the web for blocksync, I think that is the name of a script that did the same thing as DD only much faster (only writing changes), so that your downtime could be less after the initial synchronization.
