comment Why are tar archive formats switching to xz compression to replace bzip2 and what about gzip?
@illuminÉ resiliency can't be provided without sacrificing compression ratio. It's an orthogonal problem, and while tools like Parchive exist, for distributing the kernel TCP's error handling does the job just as well.

"speed" makes for a muddled answer, you should refer to compression speed or decompression speed. Neither pixz, pbzip2 or pigz are installed by default (or used by tar without the -I flag), but pixz and pbzip2 speed up compression and decompression and pigz is just for compression.

need to use -t memory (implies -t16 -t17) to get enough detail. -t16 only shows maximum capacity. also these run as root

comment Should LVM partitions be used in virtual machine images?
Just to clarify, it seems like you were asking about using LVM on the guest side. It's much easier to manage if you use LVM on the host side, pass one disk or two, and use them without any partitioning on the guest.

It can't be solved from your post, but with ssh access it isn't too hard. It's more indirect than the obvious suggestions; think about the rest of the permission bits.

comment Stripping null byte blocks with a sparse file?
That question and answer are a bit unclear, but I think they show a fundamental misunderstanding. If you overwrite a file using cp, the overwritten file disappears. It doesn't matter if that file used to be sparse; these things are not contagious.
