bootable ext. USB SSD for backup

[Matthias Apitz]

Hello,

I have acquired a small and flat USB 3.0 external disk (must be SSD for
the size of the case):

Mar 16 19:36:54 c720-r314251 kernel: da0: <TOSHIBA External USB 3.0 5438> Fixed Direct Access SPC-4 SCSI device
Mar 16 19:36:54 c720-r314251 kernel: da0: Serial Number 20170114010787F
Mar 16 19:36:54 c720-r314251 kernel: da0: 40.000MB/s transfers
Mar 16 19:36:54 c720-r314251 kernel: da0: 953869MB (1953525164 512 byte sectors)
Mar 16 19:36:54 c720-r314251 kernel: da0: quirks=0x2<NO_6_BYTE>

Ofc it has not the promised 1 TB volume, just only 953869 MB, i.e. only
1 Marketing-TB;

I'm thinking in re-partitioning the disk (which is actual only one big
NTFS slice) with gpart(8), install even a kernel into a small FS at the
beginning and keep the rest as a big UFS for backups. Having it bootable
with a system could be handy if one has to rescue a system and restore
the last dunp.

Any ideas/comments
