Simon,
If you read back through Rick's post you will see that he did take a backup BEFORE the site change, but it had some form of corruption. ergo the site had to be backdated to a previous backup that was two days older
I'd not read that bit, Sorry Rick; However the comments do still stand.
Full backups you just "go back to" and then re-apply incrementals to; for example I do a full backup of my PC once a 1/4 to DVD and I also run a mirror drive for my main C and Z drives to an external Y drive for the really important stuff; I also take incremental backups monthly or after I have new and important stuff. Would not want to loose the spec to my new boat would I
