How to use C# to backup and restore the Mongodb database? For now there is only an server to save the mongodb data, and I want to make an backup in case of the server is destroyed so that I can restore it. Dose anybody know how to do that using C#? Prahlad Yeri If you just want automated backups, there is an easier way than resorting to a full-fledged programming language: http://docs.mongodb.org/manual/tutorial/backup-databases-with-filesystem-snapshots/ As shown in the link, the below command would suffice. You may put it in a statup-script/daemon to execute it at regular frequencies: Backup

I have a MySQL Database of about 1.7GB. I usually back it up using mysqldump and this takes about 2 minutes. However, I would like to know the answers to the following questions: Does mysqldump block read and/or write operations to the database? Because in a live scenario, I would not want to block users from using the database while it is being backed up. It would be ideal for me to only backup the WHOLE database once in, say, a week, but in the intermediate days only one table needs to be backed up as the others won't change. Is there a way to achieve this? Is mysqlhotcopy a better

I'd like to programmatically make a snapshot of a live filesystem in Linux, preferably using LVM. I'd like not to unmount it because I've got lots of files opened (my most common scenario is that I've got a busy desktop with lots of programs). I understand that because of kernel buffers and general filesystem activity, data on disk might be in some more-or-less undefined state. Is there any way to "atomically" unmount an FS, make an LVM snapshot and mount it back? It will be ok if the OS will block all activity for few seconds to do this task. Or maybe some kind of atomic "sync+snapshot"?

I have an AppEngine application that currently has about 15GB of data, and it seems to me that it is impractical to use the current AppEngine bulk loader tools to back up datasets of this size. Therefore, I am starting to investigate other ways of backing up, and would be interested in hearing about practical solutions that people may have used for backing up their AppEngine Data. As an aside, I am starting to think that the Google Cloud Storage might be a good choice. I am curious to know if anyone has experience using the Google Cloud Storage as a backup for their AppEngine data, and what
