This sucks, indeed. I can't understand why they do that (maybe as an option, I could see occasional uses, but as default?). Stefan

Sure, that should work OK. I've done this lots of times. Things to consider: 1. Be careful to back up including file permissions and ownerships etc. 2. Try to copy things from a quiet system (single-user mode or similar) to get a consistent backup copy. 3. There are a *few* things that might need fixup on the new machine. You've already identified grub and fstab. For some unknown reason, network configuration (wireless networks etc.) in NetworkManager includes the MAC address of the local NIC too, so you may need to fix those up after transfer. -- Steve McIntyre, Cambridge, UK.st...@einval.com "We're the technical experts.

You should check that the newer laptop boots the same way (looks like BIOS) and that you're partitioning the same way (probably MBR). Otherwise: UEFI booting would require an ESP (and complicate setting up Grub), GPT partitioning (with BIOS booting) would require a BIOS Boot partition. Cheers, David.

Will this work? probably, depending on your method. I frequently copy the desired partitions (without modification) with Gparted to a separate physical drive... installing and updating GRUB is the only stumbling block.

Backing up whole Debian installation from laptop to laptop via ssh?
I have an old Thinkpad on its last legs which I cannot shutdown (long story). Then I have a slightly better Thinkpad with similar hard drive. Debian is split into three partitions (root. home and swap)/ I'll recreate a similar partitioning from a live usb on the newer laptop, then I'll mount the root partition, connect to the old laptop via ssh, copy the data on the new drive, reinstall grub and modify fstab.
