Exporting Xen Server Virtual Machines Assistance

We have a Dell Poweredge server T710 running free Xen Server 5.6 edition.  We are having an issue where the RAID 5 Array has a puncture in the array and Dell is telling us we need to blow away the array and rebuild it.  They state Image level backups will not work because they copy all the way down to the logical sectors of the hard drive and if they are restored on the new recreated array that we will just copy the puncture back onto the drives, so we have to do a file-level backup.

What can we do to minimize down time?

Yes, in such case you have to do a file level backup.
Image level backup will also record the RAID issue so when you restore this backup it will also restored the RAID issue again.

Best way is to take a file and folder level backup which only copy the file and folder not the disk structure.

Yes I understand that, but what about moving forward with this, what process would you recommend?  There are 4 server vms on here.  Would exporting vms work?  Then reimporting vms after we rebuild the array?

Yes no problem with the import and export.

These servers are live server I hope, so take a backup of these servers also ( you may use storage craft for the same or any other server which can do it faster)

Be in safer side.

Yes these are live servers.  One running exchange.

So we export to like a usb drive, rebuild drive array, reinstall Xen server, reimport server vms, boot up server and we are golden?  That sound like what we need to do?

Yes thats it and there is no other option as RAID is on risk.  Also I suggest don't delay in such situation.

Best of Luck.
