CouchDB backups and cloning the database

阅读更多关于 CouchDB backups and cloning the database

问题 We're looking at CouchdDB for a CMS-ish application. What are some common patterns, best practices and workflow advice surrounding backing up our production database? I'm particularly interested in the process of cloning the database for use in development and testing. Is it sufficient to just copy the files on disk out from under a live running instance? Can you clone database data between two live running instances? Advice and description of the techniques you use will be greatly

Is there (an automated) way to backup Hudson CI files?

阅读更多关于 Is there (an automated) way to backup Hudson CI files?

Here at my company we have three Hudson CI servers with 100+ jobs configured. We are looking for an automated way to periodically backup job configurations and build history. Currently we have an ant script that we configure as a job but it's not easy to maintain and not elegant. Have any of you found a way to manage this? There is a Backup Plugin . I don't believe that it supports scheduling of periodic backups, but you might be able to trigger it by accessing it through the URL (like some other Hudson remote APIs), in which case you might be able to simply set up a cron job to ping the URL.

what is the proper way to backup/restore a mnesia database?

WARNING: the background info is pretty long. Skip to the bottom if you think you need the question before the background info. Appreciate the time this is gonna take! I've been all over the web (read google) and I have not found a good answer. YES, there are plenty of links and references to the Mnesia documentation on the erlang.org site but even those links suffer from version-itis. So in the simplest case where the node() you are currently connected to is the same as the owner of the table set then the backup/restore is going to work. For example: $ erl -sname mydatabase > mnesia:start(). >

How to decrypt an encrypted Apple iTunes iPhone backup?

阅读更多关于 How to decrypt an encrypted Apple iTunes iPhone backup?

问题 I've been asked by a number of unfortunate iPhone users to help them restore data from their iTunes backups. This is easy when they are unencrypted, but not when they are encrypted, whether or not the password is known. As such, I'm trying to figure out the encryption scheme used on mddata and mdinfo files when encrypted. I have no problems reading these files otherwise, and have built some robust C# libraries for doing so. (If you're able to help, I don't care which language you use. It's

Automatically Backup MySQL database on linux server

阅读更多关于 Automatically Backup MySQL database on linux server

I need a script that automatically makes a backup of a MySql Database. I know there are a lot of posts and scripts out there on this topic already but here is where mine differs. The script needs to run on the machine hosting the MySql database (It is a linux machine). The backups must be saved onto the same server that the database is on. A backup needs to be made every 30 minutes. When a backup is older than a week it is deleted unless it is the very first backup created that week. i.e out of these backups backup_1_12_2010_0-00_Mon.db, backup_1_12_2010_0-30_Mon.db, backup_1_12_2010_1-00_Mon
