mystery disk usage growth spurts

Hi -

According to PCP archive data [1] [2], over the last few weeks, something
or someone over at sourceware's /sourceware1 partition has consumed
quite some room, in three bursts of some 90GB each:

2016-02-11 12:50-15:00
2016-02-19 13:30-14:20
2016-03-01 18:25-19:25

The irregularity of the schedule makes it unlikely to be a cron job.
Disk utilization curves from the same time make it seem like a
-copies- are being made as opposed to new content.

Does someone have any suspects as to where to start looking?

I checked ~ftp/pub/gcc, and that only had 30G in total (which I
brought down to 22G by removing older snapshots).

/www/gcc/ is at 53G, which first surprised me, but includes all
mailing list archives and online documentation, and clearly is
not the source of what you are looking for.

Nothing crazily large under /home or /log, either.

How about ~cygwin ?

% du -s ~cygwin | comma

Excellent guess:

% du -s /sourceware*/cygwin-staging/jturney/*/*
80170548        /sourceware1/cygwin-staging/jturney/backup/20160211121400
80817956        /sourceware1/cygwin-staging/jturney/backup/20160219132504
82844828        /sourceware1/cygwin-staging/jturney/backup/20160301182520

Jon, please clean up & take steps to prevent such a buildup.  Thanks!
