Questions about verification

Recommended Posts

I have many laptops to backup now. Backing them up to a new bkupset takes quite a long time especially if they're on wifi and many times that backup is incomplete because they go off network.

Example:

Quote:

Trouble reading files, error -519 (network communication failed)

12/5/2007 4:47:48 PM: Execution incomplete

Remaining: 1155 files, 161.3 MB

Completed: 32114 files, 17.0 GB

Performance: 68.7 MB/minute

Duration: 04:18:05 (00:04:53 idle/loading/preparing)

 

 


 

Now the verification does not happen in this case (even if it is set to only MD5 which seems silly because it should already have the hashes to compare)

Next time they're in the backup it completes but it only looks like it verifies the remaining files that were backed up.

 

How can I be sure all the computers files are there with out verifying the entire set?

 

Kindly,

Yes this is a nice feature. A couple of points of interest though... The "Verify only backups not previously verified" option seems to refer to those verified by the scripted verify and not those that might have already been verified as part of a scripted 'backup' you did earlier.

ie. "backup using media verification"

In other words the first time you run this script against a particular backup set you will be verifying the entire set anyway and then subsequent scripted verifying will be shorter using this option. blush.gif

 

The second point is the output found in the log. How can this be helpful when it doesn't indicate the particular snapshot or client source that this refers to?

Generated MD5 digest for file "C:\WINNT\outlook.pst" does not match stored MD5 digest.

 


 

That being said I can definitely see this being a useful feature when performing new or recycle backups and just verifying them at a different time. Just make sure your "Preferences > Media Verification" is set to Generate MD5 digest at the time of the backup. It is by default.
