I get a few people that I know asking about backup solutions for home, so I thought I would put document what I use and works well for me.
What I needed was a solution that would allow for the following:
1. backup multiple iterations
2. allow for centralized backup for multiple computers
3. simple to use (I am a simple person)
What I ended up with was the following:
1. D-Link DNS-323 2-Bay Network Storage Enclosure
2. WD 500GB Drive (bought a while ago, so increase as needed)
3. Tivoli Continuous Data Protection
Now I know you all are going, "of course you went with a Tivoli product", but I downloaded the trial and was quite pleased with how it worked and did the tasks I needed it to do.
Here are some screen shots
This is the Start page for TCDP. I have meshed together the flyouts for the My Files, Local Storage and Remote Storage to show some more info.
The General Settings (Accessed from My Files flyout > Settings) allow for some configuration options such as where to backup locally, how many iterations and how much space to use.
In the Files to Protect settings, you can set the files/directories to include and exclude.
Email protection will allow for some various email programs for backup.
Remote Storage allows for TCDP to backup files to a remote storage device. In my case it is the DLINK NAS as listed above.
Advanced Settings allow further configuration to tune TCDP
As files are modified, TCDP will back them up locally and remotely (if available). Below is the Report feature that shows the image files I used for this blog being backed up. The popup in the screen occurs when you click on the Date/Time for the row that you want to see to provide more detail.
I really have not noticed any performance impact, but you also have to look at what is being backed up. I made sure to exclude any of the VMWare extensions and a few others that I know I do not want backed up. This is just like setting exclusions for Antivirus software :)
The restore is also quite simple and will allow for selection either from the local or remote source. When restoring, you have the option of restoring to the original location or to a new location. I would put screen shots for the restore steps, but this one is getting long enough already.
The backup and restore does work, and works well, I tested it out recently after someone had their drive crash with all their pictures. I wanted to make sure this worked!
There is a "demo" on IBM's site at http://www-01.ibm.com/software/tivoli/library/demos/cdp.html?S_CMP=rnav, but it is more of a high level of what the product does rather than a look at using the actual product.
Now the only issue I have with it is that there is not currently a linux client, which may or may not be a problem for you. It is not a big deal for me as anything linux I have does not really require a backup solution.
