Migrating all my Data from one server to another in order to clone it...
So I have two servers that are almost identical. I would like to set up a backupserver in case something happens to my production server. I proceeded to dd the harddrive on my production server into a portable usb drive and now I would like to pass all that data back to my backup web server.
What would be the best way of doing this? should I just dd from the usb drive to the regular harddrive using a liveCD? also how would I go about setting up the fstab? ---------------------(my usb drive)------------------ Disk /dev/sda: 255 heads, 63 sectors, 30401 cylinders Units = cylinders of 16065 * 512 bytes Device Boot Start End Blocks Id System /dev/sda1 1 30401 244196001 83 Linux ------------------------------------------------------ Disk /dev/hda: 255 heads, 63 sectors, 4866 cylinders Units = cylinders of 16065 * 512 bytes Device Boot Start End Blocks Id System /dev/hda1 * 1 6 48163+ 83 Linux /dev/hda2 7 3167 25390732+ 83 Linux /dev/hda3 3168 3330 1309297+ 82 Linux swap /dev/hda4 3331 4866 12337920 f Win95 Ext'd (LBA) /dev/hda5 3331 4784 11679223+ 83 Linux /dev/hda6 4785 4833 393561 83 Linux /dev/hda7 4834 4866 265041 83 Linux --------------------------------------------------------------------- One more thing, while using dd to pass all my data to the usb drive I encountered a couple transmission problems such as: [root@internal init.d]# dd if=/dev/hda5 of=/dev/sda1 dd: writing to `/dev/sda1': Input/output error 129+0 records in 128+0 records out Will this have a negative effect on my backup? Thanks a lot!! |
Hello,
Do the two servers have connectivity to each other? If so try taking a look at "man rsync" and use rsync to backup the files to the backup server. Rsync will allow you to automate the process and not worry about CD's and/or usb drives. -Raymond |
I did take a look at rsync but I was trying to clone the server itself that is why I took the dd route.
