Create a separate partition for snapshots during Linux Mint installation ?

Post by Dupo » Sun Jul 15, 2018 7:23 am

Hi everybody,

I would like to create a separate partition on my internal disk (EmmC) that would be similar to a Windows recovery partition. That Linux partition (ext4) would only be used for snapshots. Is it a good idea ? How much space should I allocate to that partition knowing that the disk is 64GB, that it contains an uefi partition of a few megabytes, and that I plan to create a root partition of at least 32GB (/home included).

Thanks.

Good idea, yes. Give it a minimum of 10 GB, that should be enough for the (big!) primary snapshot plus a few extra. Do the partitioning beforehand, with GParted, after booting from the Mint DVD.

Would Dupo really need a minimum of 10 GB for a 64 GB eMMC storage?

From my limited experience with Timeshift, I've learned that the primary snapshot can take up to 8 GB...

it would really depend on the size of the / root partition,
as one would assume that the backup partition may need to be at least as big as that / root partition,
and maybe plus a bit more, as well.

in my experience, on MX the / root files occupied around 3500MB, but on LM the / root files occupied around 4500Mb.
but, generally speaking, I've made the partition at least double that, in size, or about 7 - 10 GB ..
& it does also seem that the latest version of both system, are now even bigger than ever.

Dupo, that is a great idea! I probably will do the same when I install 19 (I run 18.3).

If you can spare ~10 GB out of the 64 GB, kudos!

@Pjotr and/or Pierre: TimeShift doesn't have a compression option? I can't check because I don't have Mint on hand.

Timeshift does no compression of its own, no. You can backup to a compressed BTRFS mount though.

Hi everybody,

thanks for your answers. :wink:

I think I will only perform a primary snapshot after the installation of Linux Mint (Like the Windows recovery partition on pre-installed WIndows machine). So I could restore the system in its original state if there is a big problem. As you suggest, I will give a minimum of 10GB disk space for it.

What do you think about my idea to including /home in the root partition ? I will use an external memory card to store all my files (documents, music, videos, ...).

Thanks for your help.

Regards.

I do it and I also include /home in my Timeshift snapshots. I don't use /home for personal data. All it contains are preferences and program data.
