  • power of dd

    From Benny Pedersen@2:230/0 to All on Sun Sep 12 21:20:14 2021
    Hello All!

    its my first time doing an image with dd, so now i have to try rufus to write it out on a usb pin :)

    if succes bye linode.junc.eu

    story behind, linode was the first vps i created servial years ago to get all my hosting content out of adsl, lol, yes i started with email at the date of adsl widt 512K/128K bit uplink/downlink, it had even homepage served later then its speeds gone raced to astoning speeds of 1Mbit/768Kbit, that was time. now my home fiber optical is 20000Mbit, where was this cable when i had a need for it ?


    Regards Benny

    If your network connection is so fast, it would have been better to tar the files and copy or even use rsync over ssh.

    If you use dd on a whole disk, your image will be that size. a dd of /dev/sda1 that is 10gb will leave you with a 10gb image.

    with bzip2 its not that big, but yes its not convense to use big partions with dd, but it got the job done without loosing any data from the old host with is basicly good when one dont remember where the custom things is hidded from the start, now i can find later without stay paying to linode for that vps

    yes

    that is 10gb will leave you with a 10gb image.

    the dd file can live be compressed while in transfer, so there is not need to be transfered 10gb

    Speaking of dd power - I used to have in the past script to migrate VPS (eh, ok, they gave VPS for one month for free and I wanted to save money) - I migrated VPS every 4 weeks.

    Beside booting to rescue on both (and some fstab fix), main command was:

    xfsdump -l0 - / | gzip -c | ssh root@new_ip "gunzip -c | xfsrestore - /"

    Local network speed within one host was amazing ;-)
