Symantec Backup Exe 2012

I have a Buffalo Tera Station NAS 6TB,
I'm using BUE 2012 to do full backups
I want to simply over write the backup of the day before.
So if I backup tonight, when it backs up tomorrow, I want to use the space that was used for the backup, not append ( add ) or use up more space.
I know that BUE 2012 has a new setting to first check to see if the new backup is a good one and then delete or write over the old backup on the next backup the following day. It's not working for me.... Maybe I'm understanding it wrong???
I have called Symantec Tech support and spoken to appro 4 diff techs, some seem to be more lost then me.
Any one knows exactly how it should work or can explain how I can set it up s that it dose what I want it to do.

Thanks all...

have you created media sets?

create a new media set and associate the drive to the media set and point your rotation to that media set.  When creating a media set you have the option for a retention period.  you can set this as 4 hours.  when the media set is set longer, then it wont overwrite.  there also should be an option where you can set the back up "overwrite when there is no available space" (or something of that nature)

a work around
create a rotation to erase the drive before the actual backup begins.  

hope that helps

I can't create a Media set, when I was backup to a tape drive it allowed me to create a media set, but as of the time that I started to use the Buffalo NAS it dose notNo Option for Media Set give me the option.
Also I have the backup job to be retained for one (1) hour.
Retain for one hourAnd I also have the storage set to allow overwrite.
Over writeStill the space on the NAS continues to be added to instead of reusing the spaced that the first backup was written too.
Any ideas as to what is going on?
Never had a problem with Symantec using the backup until I started to use 2012.

Thanks

when the storage is maxed out...does it then start to overwrite?

try catalogging the media and inventory it so it wont be set at scratch media.

Honestly don't know
Now that you brim it up, that is why the tech said. But we also made a change to the reg to prevent that and it's stil appending and not over writing.
You think that's the case. I will over write once it's full?

ok....lets try this

get a new machine....or a machine that you can use without causing harm to your network.

join machine o domain as normal...fixed IP etc etc etc


Install server 2008 on it....then install SBE 2012....

format your external and treat it as NEW
create the rotation
run the rotation
if it works that means that the server is the issue

if the issue still happens then its either the external drive or the software.

seeing that this is the first case like this...you should consider that the drive may be the issue.

you should want to try another brand of external just for testing purposes.

thats the best i can give on this situation

chubby_informerCommented:
yes i also think thats the case....the drive is not full so it has nothing to overwrite

Should it not over write what on the drive now?
It over wrote the backup tape and that's the same thing...
The problem started when I switch from BUE 12.5 to 2012.
In 2012 they changed how everything works.
I even have some customer on a NAS ( same Buffalo ) and all is working correctly, except that they are still on BUE 12.5, not BUE 2012.

chubby_informerCommented:
then best advise is to lodge a complaint with Symantec....revert to 12.5


rules in IT :D
1. If its not broken....dont fix it!!!
2. Prepare for it to be broken

Pretty sad...

OK,
So here is the skinny on how backing up to a NAS on BUE 2012 goes.

1- You can not create a Media set if you are backing up to a NAS ( only tape )
2- When you create a backup you have the option to give it that amount of time that you want to retain it for ( 1 day, 1 week ect.. )
3- BUE 2012 have a service that runs every 4 hour's and it looks to see if your backup retention time is up, if it is it will delete it, but only if there is a valid full backup, if there is none it will not delete the backup even if the retention time is up.

I hope this helps for other people in the future, it took 4 day's of trouble shoot with Symantec tech support it was not until today that I spoke with a Senior that it was explained to me how it works.

lol....glad the issue was resolved....congrats...SBE is still a great product

noadAuthor Commented:
I agree SBE is a great product...
I would just hope that there first line level tech support get better training, it took me 4 day's to be able to speak to a Senior tech support and get the correct answer. I lost approx 1 day of my life dealing with this issue which was very simple.
The true test will be in a few day when I really see that it's working like I was told it will.

Again,
Thanks for all of your help and suggestions.
