You should have no trouble decompressing it. xz is widespread at this
point, many of the big Linux distributions and at least FreeBSD use it
to compress their packages now. It has the same command line interface
as gzip (xz -c/-d, unxz, xzcat, xzless etc.) and recent GNU and BSD tar
are both xz-aware.

Package xz-utils in Debian flavours, xz everywhere else that I know of.

It is astonishingly space-efficient given CPU and memory aplenty during
compression. On large repetitive log files I regularly see compression
ratios of 1000:1, megabytes in kilobytes. Maybe the reason I haven’t
seen even higher ratios is just that I haven’t fed it files big enough.

Decompression is fast and cheap no matter the compression level.

Try it, it’s great.
