Okay here i go
In Windows 2003 there was :
Full - Back up files - Using archive bit (reset archive bit)
Differential - Back up changed files since last full - Using archive bit (does not reset archive bit)
Incremental - Back up changed files since last full or incremental - Using archive bit (reset archive bit)
Now On Windows 2008 There are 2 Choices.
VSS Copy Backup Which Does not Clear the Archive Bit.
This means that Files that have been Changed their Archive Bit is Activated and WBS Backups this Files and does not clear the Archive Bit (Application Logs) So when a Secondary Backup Software sees that their Files Archive Bit is Activated it Backups Them. Correct?
VSS Full Backup which Clears the Archive Bit
This means that Files that have been changed their Archive Bit is Activated and WBS Backups this files and Clears Their Archive Bit (Application Logs) So When a Secondary Backup software if we made that Mistake to have Secondary Backup Software and Choose VSS Full Backup sees that files that Archive Bit is not Activated so it consider that Files have not been Changed and does not Backup Them. Correct?
Pls Understand me i have many Difficulties on my english and am keep Trying thats why i ask simples Questions.

Don't worry Nicolas, your english is better than my greek. I only had to read this three times ;-) Looks like you got it right.
Regarding the previous thread: Mark is right, the commandline tools are better for serious use. The GUI isn't finished. The 2008R2 (build 7000) version has a few improvements. One of them is an intriguing "bare metal recovery" that I yet have to try.

Forgive me for putting my oar in...
Nikolas, I've done a bunch of testing on that thing and the GUI's label is one hundred percent wrong. My testing shows that it doesn't do a single thing on the archive bit.
What it REALLY does is to include or exclude the "previous versions" and "system restore" information in the backup. It's only relevant to bare metal recovery. (Which is an amazingly cool feature, I've used it!) |

Shrug. As my questions are partially related to this thread, I hope you won't mind me hijacking it a bit later on.
So, I almost thought I finally understand how WSB works, but I guess not...
Mark (or anyone), which option in the GUI (VSS Copy/Full) contains the previous versions and system restore info? And how do those 2 GUI options relate to the -vssfull option of wbadmin?
Give the way WSB works, we decided to "full" backup, so we can use it for both DR scenario (Complete "PC" restore) and normal backups (to be able to restore files/directories).
Also if you use wbadmin, you can use local drive and keep its drive letter and other content on the disk. If you use the GUI, the disk is formatted and drive letter is removed ... as the documentation says... reasoning being backup consistency.
So, what's the difference really? I'd prefer wbadmin method, because I can use the drive for other purposes too, but the GUI simplifies scheduling the tasks (unless you're limited by the options it provide).
And last one - regarding WSB and backing up SQL server - SQL server has VSS writer, so it's VSS-aware app. What does it mean in reality - if I backup server with SQL server, will the SQL server be in consistent state if I do "Complete PC restore"? What happens to transaction logs during WSB backup? Regarding the previous paragraph - backing up with wbadmin will for example allow me to store SQL DB backups to the same disk where WSB backups are stored (not possible with with the "GUI way") - feasible or not? |

For SBS use the Backup wizard, and take the lot.
For the Standard server, unless you have specific requirements, then I'd take a VSS Full Backup, you never know when you'll want to restore to a VM/ other piece of hardware.

| I have read the microsoft help files and several threads about this and am still trying to figure it out. It sounds like VSS Full Backup is the one to use if you want to use bare metal recovery. Is this correct? The GUI lets you choose bare metal recovery even if you say VSS Copy Backup. Is it that the bare metal recovery will get it to a more up-to-date state (including more recent changes) if you use the VSS Full Backup, while bare metal recovery will still work but not be as up-to-date with VSS Copy Backup? Thanks. |

Hi Bryan -- as far as I can see -- and I've done a lot of looking at this -- "-vssfull" has NOTHING to do with being able to do bare metal, either will provide BMR.
The only difference is the resulting VSS on a system that you've restored from the backup. Thus, let's say that you must do a BMR. You now have a server that acts just like the one that died. How many generations of files can be undeleted from VSS, one or many? That's what -vssfull does. I hope this helps. |
