Restore Specific Files from a Huge .BKF NTBackup.exe file

I like using NTBackup.exe on the old VMs, but discovered that if you don't keep up on the backup rotations, you will have a very hard time doing restores. The NTBackup.exe restore doesn't make it easy to restore all incrementals of a folder.

My Favorite Backup Device: Raspberry Pi NAS

Last year, I got one of those little Raspberry PI (R-Pi) devices. It's pretty cool, but in the end it's a little PC. Since there's a big bad PC under the desk, the R-Pi didn't get much use. Also, I'm a chicken hardware hacker and so I never put anything onto the GPIO pins.

NAS Backup Awesomeness

We have this old Terastation NAS, and it's been solid, but I just figured out that it has support for an external USB disk, and it's easy to set up to backup to the external USB disk. Right now, we're using around 1TB of the array, and it's being backed up to the external disk once a day. The backup is done with Rsync, and it takes around 10 minutes.

TeraStation 2: adding usb hard disks for backups

We got one of these at work years ago as a backup unit, and it's been working well. Exactly one disk error in years and it fixed itself, basically. However, as disks age you know they are going to fail, taking your data with it. So the only fix is to proactively replace them, and also run backups. I thought that it would be easy to add a backup disk, because there are USB ports on the terastation. That was not the case.

I recently had a RAID5 array fail, and learned something about backup: it's not just about the data, but also the recovery time.

Distributing a Large IMC Website P2P

It's always a concern that an IMC can be taken offline. As the sites get larger, it's more of a challenge to keep it backed up and distributed. There's also the problem of software upgrades.

How to Make Unix Backup Scripts with rsync

Rsync is a good way to create and maintain a "mirror" of specific folders on your unix system. It's not good for archiving, for cloning disks, or running a "full/incremental" backup system.

What rsync does is compare two folders, and syncrhonize them.

The following command will backup my home folder to an external disk called "/media/extdisk".

rsync -a /home/johnk/ /media/extdisk
