12/24/2023 0 Comments Smartsvn over network![]() In the network environment, all access to the database is running roughly 100 times slower than the developmentĮnvironment. I recently deployed theĪpplication to a new Windows 7 client on a gigabit network connected to a SQL Server 2014 instance running on a Windows Server with tons of disk and RAM. Performance in the development environment is great. The application uses a combination of Entity Framework, LINQ, and T-SQL. The next time we cover this topic, I’ll show how to automate these same backups with the help of cron.I have a C# application developed on a Windows 7 system with a local SQL Server Express database. There is far more that can be done with rsync. That’s it! You’re ready to take advantage of rsync as a means to back up data either locally, on mounted shared directories, or over a network with ssh. Zip /data/MONDAY.zip /data/MONDAY & rsync -av -e ssh /data/MONDAY.zip Congratulations To do this, you would employ the zip command like so: Say you want to zip the folder /data/MONDAY and back it up to a remote Linux server. A little zippingĪ nifty trick you could do is zip your folders and then back them up with rsync. As soon as the credentials are accepted, the data will be transferred. Rsync -av -e ssh /data the above example, you would be prompted to enter the password for the user named “backup”. The structure of this command will look like: We’ll have to do this with a user that holds write privileges to the /backup folder on the destination (such as root or a special user you’ve created for that purpose). Say we’re going to back up the folder /data to the folder /backup on a server with the IP address 192.168.1.228. Thanks to SSH, we can employ rsync to back up those files/directories from the source to the destination…over your network. Now, let’s say you don’t want to back up locally or to a Windows share instead, you have a Linux server that stands as your backup destination. If the /data directory happens to be a mounted Windows share (mounted with a command like sudo mount -t cifs -o username:domainusername //SERVER_IP/ShareFolder /data/), then everything you back up with rsync will be found on the Windows shared directory. To read a complete list of options, issue the command man rsync. There are plenty more options, but those are the two you’ll want to know to get rsync up and running. Say, for example, you want to back up ~/TEST into the folder /data/. The command structure of rysnc looks like this: Once that installation is complete, you’re ready to go on both machines. To install this, open a terminal window (this will be done on both client and server) and issue the command: The ssh service will probably not be found. I’ll demonstrate this with an elementary OS Freya client and a Ubuntu 16.04 server both of these platforms will already have rsync installed. ![]() SEE: Data backups: The smart person’s guide Installation Because of this, I’ll first show the basics of rysnc, so you can back up directory to directory, as would be the case in backing up to a mounted Windows share on a Linux box. There is a way to use rsync to back up from Linux to Windows by adding Samba into the mix–that method requires you to have your Windows shares mounted on your Linux box and then use the rysnc tool to run the backup. The primary method I am going to show only works on Linux to Linux backups. The tools you need to pull this off are rsync and ssh, both of which are most likely already on your Linux machines.

Fortunately, you’ve chosen a platform that makes this process really easy…even over a network. If your business uses Linux for desktops or servers, you might be unsure of the best way to back up your data, or you might want to roll your own backup scripts.

Linux comes with a ton of tools for administrative tasks, including backing up over a network. How to back up over a network using rsync
