backup

问题 I am working with bigquery, and there have been a few hundred views created. Most of these are not used and should be deleted. However, there is a chance that some are used and I cannot just blindly delete all. Therefore, I need to backup all view definitions somehow before deleting them. Does anyone know of a good way? I am not trying to save the data, just the view definition queries and their names. Thanks for reading! 回答1: Part 1. Issue the bq ls command. The --format flag can be used to

问题 I'm trying to use a simple mysql database but tweak it so that every field is backed up up to an indefinite number of versions. The best way I can illustrate this is by replacing each and every field of every table with a stack of all the values this field has ever had (each of these values should be timestamped).

问题 What do I lose if I skip the .metadata/ directory when doing the back-up of my Eclipse workspace? (Is there some documentation describing what Eclipse stores in this directory)? I've noticed that it changes very often (essentially every time that I use Eclipse (Galileo). I've seen this question, but I'm not interested in doing a back-up of plug-ins and settings (also because I'm not sure that they would work properly when restored after a re-installation of my PC or on a new PC).

问题 I'd like to try out a few things with git and I don't want to screw anything up in the working repository.

问题 I lost all my photos and contacts in my iPhone, when I had to do a recovery, after I did an update. When trying to restore my old data from backup file, it prompted me for password. I have tried all passwords I normally use, but to no availe. I have tried programs like Elcomsofts password breaker.
