I updated to 2.2.0 from 2.1.2 using ./setup from the 2.2.0 tarball per instructions. At least I thought following the instructions. All my websites still work, ftp and email still works, and so does the DNS. I noticed a problem when I tried to log in my ISPConfig panel. The username admin did not exist or work. I checked the mysql database for my ISPConfig installation... and all the tables (except dns_*, doctype, sys_dep, sys_modules, and sys_nodes) had been truncated completely, as in all the rows were erased! All my usernames, isp, reseller account info seems to be completely gone. Yes I know in hindsight I should have backed this database up completely before the upgrade (my last ISPConfig upgrade went through without a hitch so I was caught off guard). Constructive questions I have now are.. Does ISPConfig by default leave any backups nightly, etc that I can find to rebuild my ISPConfig database? What could have gone wrong to cause the ISPConfig set to erase all my tables? (So this doesn't happen to others, or to me again.) Is there a way to get a default data set of ISPConfig database without having to run the setup fresh, if I cannot find a backup I have performed manually?
