Hi Gavin, I don't know either. That's the big concern for me. I suppose I can test that out.
My other thought was to take my full backups and restore them onto a USB drive so I can directly upload the contents to my datacenter. Then I could create a job to restore an incremental onto a directory then rsync it to my datacenter, then delete the local data. Just trying to figure out the best method. -Mike Gavin McCullagh-2 wrote: > > Hi, > > On Tue, 10 Nov 2009, Jesper Krogh wrote: > >> wvoice wrote: >> > However, I'd like to be able to backup the backup data offsite.
