The constant growth of TitanPad made it necessary that we think about data persistence. While I'm writing this blog post there are close to 90.000 public pads and over 45.000 pads in private subdomains. In total they take up about 100 GiB of disk space.
To slow down the growth of the disk usage we're going to delete public pads which haven't been used for a long time.
Starting with April 22nd 2012 we're going to delete all public pads which haven't been accessed in the last 12 months.
Since most of the public pads are very transient in nature we don't expect to hit major problems with this approach - if you've still got important data in public pads now might be a good time to move them into your own private subdomain!
