Comment 4 for bug 977652

Eli,

I think Michael meant to comment on bug #1003783, not this one.

As to this bug, I do not consider it as a documentation issue. I'm going to fix it in 2.0.1 by omitting xtrabackup_checkpoints from compression, so that a full backup could be used for incremental backups without decompression. I agree, it doesn't make much sense to compress it.

As to the other comments, there are 2 parts to this problem:

1) qpress can actually do multi-threaded decompression (the -T switch), and it uses 2 threads by default.
2) the dependency on an external utility to decompress backups makes the restore process confusing. To add insult to injury, qpress is unfortunately not packaged by all popular Linux distributions. So in addition to 1 more step with decompressing backups before restore, one may need to download and compile qpress before using compressed backups. I'm currently considering multiple options to make it less painful, but that will probably be implemented after 2.0.1.
