Since I have to re-send this anyway, my current laptop setup for some time is
this:
- there is one internal drive, ~750 MiB
- Root partition, ~30 GiB, Debian default Ext4
- (there's also a default sized EFI partition, may be ~1GiB from memory)
- remainder, ~700 MiB is a single data partition, which is assigned to
a single-partition zpool (zfs disk pool)
- inside the ZFS "internal" data pool, I create a number of ZFS
"filesystems", see tutorial below
- one of these holds various crypt volumes (virtual/loop mounted FSes)
- inside each crypt vol is another, nested, ZFS filesystem - snapshots
are just SO nice, I could not resist this...
On my laptops, I prefer to put all the free space into one partition,
encrypt the partition, and then put something on top of the encrypted
virtual device (usually ext4, but I tried ZFS on Linux recently).
Everything is encrypted by default, so I do not need encfs(1), etc..
There's an earlier tute and example code (bash script) and commands for
setting up this combination, but it's a little more technical than the
tutorials below, which are designed for absolute ZFS beginners. See
here:
https://github.com/zenaan/quick-fixes-ftfw/tree/master/zfs
(If new to ZFS, perhaps read the zfs tutorial below first though.)
If I had a second internal drive, this is how I would use it:
- as a single, full-drive ZFS pool
- inside would be at least a "primary user" filesystem,
I would move the large drive to the second bay, put a small, fast drive
in the primary bay, install Debian on the primary drive, and use the
secondary drive for data.
- as well as a " 'primary drive data partition' backup filisystem", to
which I would make regular backups of my primary drive data partition
I use zfs-auto-snapshot on my systems with ZFS:
https://packages.debian.org/search?searchon=names&keywords=zfs-auto-snapshot
(in my case, my primary data backups are made to an external USB drive,
but same diff...)
I would set up the USB drive as follows -- put all the free space into
one partition, encrypt the partition, and put the encrypted virtual
device into a ZFS pool.
For backups, I would replicate the ZFS filesystems from the laptop pool
to the USB drive ZFS pool.
