Hi all, I just tried "Bash on Ubuntu on Windows" (yes, it's real title). With this, there are now 4 ways of running Unix tools on Windows. 1. busybox -- single binary running on Windows. 2. Cygwin -- you download and install bunch of programs, like bash, bc, awk, sed, etc, that

If you don't test, you will have a Schrödinger's backup: both valid and invalid at the same time, until you try a restore. On Dec 23, 2016 6:20 PM, "Alvin Starr via talk" wrote: > On 12/23/2016 02:59 PM, Stephen via talk wrote: > > With the discussion about backups, I would

With the discussion about backups, I would like to raise a question I have had for some time. Having backups does no good if you cannot restore them. Files are rather easy to test. But how do you test restoring a database? I back it up with the usual tool. I have the docs to do the restore.
