PostgreSQL备份与恢复 官方文档（英文）： http://www.postgresql.org/docs/9.4/static/backup.html 官方文档（中文）： http://58.58.27.50:8079/doc/html/9.3.1_zh/backup.html 逻辑备份： 1.SQL转储（pg_dump,pg_dumpall） SQL转储不包括索引，可以自定义要备份的对象及其内容，将备份内容生成不同的格式。可以通过pg_restore还原备份。 是pg_dump的输出通常可以重新载入到PostgreSQL新版本， 然而文件级别备份和连续归档都限于原服务器版本。pg_dump是将数据库传输到另一台机器体系结构工作时唯一的方法， 如从32位变到64位服务器。 由pg_dump创建的备份在内部是一致的， 也就是说，pg_dump转储的pg_dump开始运行时的数据库快照。pg_dump工作的时候并不阻塞其它的对数据库的操作 (但是会阻塞那些需要排它锁的操作，比如多数形式的ALTER TABLE)。 Important: 如果你的数据库结构依赖于OID(比如说用做外键)， 那么你必须告诉pg_dump把OID也导出来。要导出OID， 可以使用-o命令行选项。 物理备份： 1.文件系统备份 文件系统级别备份，就是直接copy数据库目录，必须关闭服务

What causes a computer program to turn into a Big Ball of Mud ? Is it possible to recover from this anti-pattern? Are there proven refactoring methods that can be applied? A Big Ball Of Mud normally occurs because of one of the following: Change of Requirement s - You architect a solution with one set of requirements, which over time change and now, you are probably catering to a different audience who wants to use the same product with slightly different requirements. You bake those requirements into the same product and you end up with a BBOM. Change of Developers - The original product has

Okay. I used svn's hotcopy to make incremental back-ups, now how do I test that the hotcopies will work properly? I searched the posts here regarding hotcopy. Most of them seem to just be encouraging the use of the svn hotcopy, but not talking about how to recover using hotcopy once made. Is there any advice about how to recover using the hotcopy that I've made? I also checked http://svnbook.red-bean.com/ , but couldn't really find anything. Thanks. svnadmin hotcopy will always create full copies of your repository. It is not possible to do incremental backups with svnadmin hotcopy. svnadmin

I have a service for which I want to set Data value for FailureAction in registry. Currently there is value set in registry. Value is set using RegKey.SetValue("FailureActions", Value); I would like to know: 1) How these bytes of Value correspond to recovery option of service (like how to find out particular sequence in registry means setting 'First failure' as 'Restart the Service') 2) Also I need to change in registry FailureAction which will correspond to 'Subsequent failures' as 'Restart the Service' Here is my finding using trial and error method: a)Manually change setting of recovery for

Our current backup process is doing a SVN HOTCOPY every night, to a backup location on a different machine. Can I somehow recover from that backup and retain all revision history? Or do I need to use the svn dump/load? Thanks, Chandrajeet "svnadmin hotcopy" actually copies the entire repository to another location. The copy is indistinguishable from the original repository, and can in fact be used as a repository itself. So, you should be able to copy the results of svnadmin hotcopy back to your repository location and have a perfectly valid, restored repository. The advantage of hotcopy over

When I save a .m file in a folder, MATLAB autosaves a .asv file in the same folder. I opened this file and I found that it contains my code from the beginning, ignoring what I have deleted. What is the use of this file? What's the risk if I delete that file? A .asv file is just what you said, an "AutoSave" file. It's just there so that you don't lose all your code if your computer crashes/shutdown. You can delete it whenever you want. If you find them annoying you can go to File/Preferences/-->"Editor/Debugger" --> Autosave and turn it off. 来源： https://stackoverflow.com/questions/9540335/asv
