Basically what I see in lsof is a lot of:

/backup/path/mysql/database/table1.ibd
/backup/path/mysql/database/table1.ibd.tmp (deleted)

These files don't appear on disk, but they do consume space as they're deleted, unflushed files. So what's actually shown in the directory by `ls` is:

/backup/path/mysql/database/table1.ibd 90GB

But what's actually using up disk would be:

/backup/path/mysql/database/table1.ibd 90GB
/backup/path/mysql/database/table1.ibd.tmp 90GB <- (this is a deleted file)

All of these deleted files are shown as being owned and not flushed by the xtrabackup process.

I'll run another backup today so I can get some actual output from the terminal.
