So on android in 2010 I used to be into the idea of rooting my phone, and installing custom roms.

Distros are essentially custom roms for your pc. Same concept.

There was a program called TWRP that I could use. Back then it would make a full backup of EVERYTHING on your internal drive. It was mostly used after you already had a custom rom.

But it backedup EVERYTHING. If you wrote a txt message as a draft, and didn’t sent it, then backed up with TWRP, whenever you restored on a new phone, that txt draft was there too. It was literally like your phone took an all encompassing picture of everything on your phones internal drive, every single file and setting, and made a backup. Saving it to your sd card.

So I’m thinking, linux should theoretically be able to do this. Maybe it does.

What if my current install is on a 250gb drive, and I buy a completely different 4TB drive? What if I want to do this total backup, save the backup to a usb hard drive, then put in a NEW hard drive, and have it restore the backup so now my entire old hard drive is now on my new hard drive? And every setting, every file, every last detail is an exact replica.

Could I do that?

    You don’t need anything special. Just dd the old drive to the new drive and then expand the partitions.

    Yes of course, any software that makes a full image of your drive will do this. dd is the old school and very manual way of doing this. But there are programs like Veeam Agent or Rescuezilla that make it much easier.

      Really don’t understand the one guy downvoting you. This seems like helpful advice, considering my lack of knowledge.

      Unless it’s because Veeam Agent costs money. But that’s nitpicky. Costing money is for ME to decide if it’s a deal breaker. I mean, for me it is, but you giving that advice shouldn’t be downvoted. For others it may not be.

      And RescueZilla according to google is just a gui front of dd. So that sounds like my best option.

      Yup lots of options, even things far advanced like SyncThing that can safely keep things in sync between many devices and locations without having to think about it. Anyways, this is a Reddit post to see what people are using, while I wrote my own setup using rsync and dm-crypt.

    You can, and there are a number of options.

    Easiest IMO is to install both drives, and then use dd to copy drive A to drive B, and then resize the partitions with gparted to fill the rest of the disk.

    Do this from a live USB so that your not currently using drive A.

    Note that /dev/sda might not be your first disk, so make sure you get them correct. Gparted can help you identify your disks.

      Does linux have an equivalent of VSS on windows? I always thought it was odd that Linux needed to be offline to do a disk image whereas on windows I can just do it without rebooting or anything.

        VSS equivalent would be btrfs snapshots or zfs snapshots.

        Can you really copy a VSS to a new disk? For a new install, at some point you’ll need to reboot and go offline, so I don’t see the point in trying to keep uptime. If uptime matters, dont upgrade a disk, replace the entire system.

    Yes and no. Android has separate OS and data partitions. On Linux, this is configurable; in most installer defaults, root and home partitions are not separated. But it’s trivial to do after the fact, if you have some unpartitioned space or can shrink your root partition.

    However, unless you’re using flatpaks or something, it’s not guaranteed that installed programs containerize their data in the same way as Android apps.

    I Always use dd for this kind of thing. Others have mentioned some other tools but I have never had any problems with it that I didn’t cause myself.

      Oh, me causing the issue myself is a HUGE risk. I’m an idiot when it comes to linux. I would be very happy if there were a thing in linux called “guardrail”. And all guardrail would do is stop you from doing the stupid things. Like “ah, you’re attempting to fuck up. Are you SURE you want to fuck up?” And I’d be like “uhhhhhhh, imma click no for now…”

      Then later I findout I would have erased my hard drive without guardrail, or somehow launch nukes at Canada.

      What I’m trying to say is that I should still be on training wheels, but linux is all too happy to let you fall on your face.

      But dd? No idea what that is. My instinct says “disc drive”, but I could be wrong. I’m probably wrong.

        Read through this scroll a little to find your use case, it’s in there. I’m sorry if being suggested to read seems rude or uninviting or something but I really think for this it’d be faster for you to do so. These people’s articles have always helped me and I’ve been using Linux for 20 years. dd stands for data duplicator and I just had to look that up lol.

        No guardrails but you have a second to reconsider when typing your password. The other day I used some gui util as sudo and deleted my /bin folder somehow. I would have noticed that in the cli.

      Hehehe, I saw that comment before you deleted it! Aw, it’s ok. Everybody makes mistakes. hug

      I make mistakes all the time. Like…way bigger than you. I have no idea what I’m doing in life.
