License, Bugs

HashBackup has been actively developed since its initial release in June 2009.  Over that time there has been a release about every 2 weeks, on average.  There are ongoing backups of production servers from 2010 with over 2000 daily backups.

HB is being used for large production backups, often to handle offsite backup requirements in addition to an existing onsite backup.  The largest reported single backup is 53M files / 121TB at a college research site.  The itial backup took 25 days using 8GB of RAM and created 57TB of backup data managed by a 17GB database, with 22TB eliminated by dedup.  Other large reported backups are 26M files / 18TB at a research lab, 25M files / 1.5TB for a large imap server, 23M files / 34TB for a data archive, and 27TB of 1.5TB VM image backups using less than 1TB of backup space after dedup.

How is Development Funded?

I sold an Internet business in 2005, have income from other projects, and fortunately, am okay financially.  
Making money is nice but it comes with a lot of hassles, and right now I'd rather focus on creating a great backup program.

Bug List

"Is there an online bug list?"

Bug lists often provide a comfortable home to bugs for many months or years.  But most customers would prefer that bugs are squashed rather than taking up residence on a bug list, so HashBackup works a different way: when a bug is reported, it's fixed, described it in the Changelog, released, and a reply is sent asking the customer to do an hb upgrade.  If it's a difficult bug, and most aren't, an update may be sent directly to a customer asking them to verify that the problem is fixed before doing a release.

Bug reports and correcting bugs take priority over new development, so not having a bug list also acts as a self-regulating mechanism to balance development and stability.

If you have any other questions, suggestions, or concerns you'd like to discuss, send an email!  It's always helpful to get feedback about HashBackup.
