I believe that it can resize partitions and so on, at least for the linux-oriented ones. I'm not sure if it can resize NTFS. I think it uses partimage (which I'm guessing is related to partclone), which uses free-space mapping combined with block-level backups. That makes it good for backing up filesystems where full drivers are not available - as long as the software can figure out which blocks are discardable it can do a block-level backup efficiently without the need to completely decipher the filesystem layout. -- Rich

It's only faster if your disk is almost fully used. If you have a lot of free disk space your method is doing a dumb clone of unused space. So it's argueable which method is faster ;) Your method neither allows changing of partition sizes nor a change on the underlying filesystems. Maybe it's worth thinking about about another filesystem, when you switch from classic HDD to SSD. Cheers Andreas

Seriously, I'm worried that the number of hard links could push the system into thrashing, at which point an rsync will appear to die ... (been there done that). Brute-force copying the partition just seems so much easier than worrying about the contents of the file system on it. Cheers, Wol

This preserves hard links (given that the target system supports them. I honestly don't think that a dd is necessary. I have copied several times from one harddisk to another with different harddis partition sizes, but with enough free space on the target. I do the copying by booting a live usb stick, then I mount the source and the target partitions, and issue the rsync command (If you need extended attributes to be synced too, then there is an option for rsync too, e.g. ACL). rsync -aH --numeric-ids /path/to/source /path/to/target/ Cheers Andreas

Personally I'd leave Windows on the slow disk to discourage you from using it ... :-) Are you trying to replace a 2.5TB hard drive with a 2TB SSD? You can't fit a quart into a pint pot! Anyways, recreate the partitions on the SSD, then copy them using dd. Assuming your SSD is the new sda and your old drive is sdb, dd if=/dev/sdb1 of=/dev/sda1 MAKE SURE you get the drives right, or you'll trash the system! Make sure also that the new partitions are the same size or larger than the partitions you're going to replace. Then live-boot into the new drive, and re-install EFI or whatever it is you do to boot off that. I'm planning to migrate my system soon, but I'm going to do that a bit differently. I'll dd my home partition across (I've got hard-links galore, so a cp or rsync or whatever will have massive conniptions). Then I'll re-install gentoo, re-emerge all my programs, and re-create etc/passwd and all the other configuration stuff - I haven't really messed about with most of my config, so that isn't a problem. Cheers, Wol
[gentoo-user] NVM on Gentoo Linux?
Hi people, I get a 2TB NVMe M.2 for my machine, and I want to replace my very slow harddisk with this SDD. I got the 2.5 hd, with (of course) Gentoo Linux and Windows 10 This is my partitiion layout: Device Start End Sectors Size Type /dev/sda1 2048 1023999 1021952 499M Windows recovery environment /dev/sda2 1024000 1228799 204800 100M EFI System /dev/sda3 1228800 1261567 32768 16M Microsoft reserved /dev/sda4 1261568 819202047 817940480 390G Microsoft basic data /dev/sda5 819202048 821155839 1953792 954M Linux filesystem /dev/sda6 821155840 918812671 97656832 46.6G Linux filesystem /dev/sda7 918812672 1114124287 195311616 93.1G Linux filesystem /dev/sda8 1114124288 1145374719 31250432 14.9G Linux filesystem /dev/sda9 1145374720 1172328447 26953728 12.9G Linux swap I'd like to mirror everything on the NVM and boot from that, with my existing Grub configuration Can somebody of you give me a good starting point ? I think it has something todo with systemrescuecd which I would prepare on a USB stick and ... ... ... For any advises I would kindly thank you. best, Tamer
