Thank you for your help, but the link can't connect to related KB
Hi,
Check your OPP and Append settings on your media set/s. This allows your media to be overwritten to correctly.
If not, it continues writing new files until the B2D runs out of disk space.
Check the Symantec TN on this, and also make sure your B2D is set to be overwritten, not appended too.

Thanks!
If you find this is a solution, please mark it as such.
Thank You for your help,
I don;t know why the solution document link is not work...
As you said, set as overwritten, that I can't keep my data and will overwrite everynight?
this is a Differential schedule and would like to keep 7days.
I don;t know why it created a 800G size, I can't have a size setting on that?
Thanks
No it won't. those files are ptorected for 7 days. All you are setting there is that they don't append. When you do it causes issues with the backups and catalogs etc.
Check your B2D settiings, and make sure you've selected the default of 4GB (or something slightly larger than that). It may be that you inadvertantly selected a setting of 800GB for your B2D files, in which case it creates it as 800GB, not multiple files of say 4GB.
It's a larger file and easier to manage, but if the file corrupts, you lose everything in it. 10GB should be about the largest you select for performance and manageability.
If you find this is a solution, please mark it as such.
I see,
For example:
If I set it as 10GB, the data backup total have 35GB,
then the result is will be create 4 set of 10GB .bkf files?
Thanks
For .bkf files, you can control the max size by setting the max size property of the B2D folder. For .img, they will be as big as needed to hold the image.
Do you mean this settings?
That can fix the max size for every bkf?
Yes. This will set the max size for all the .bkf files. You should not check the Allocate max size box. If it is checked, BE will allocate the max size even if it needs only 1 kb.
Thank You for your help,
let me try it again,
When you change the max size parameter, it will not take effect immediately. Only when the .bkf is being overwritten or a new .bkf is allocated, then the new max size parameter will take effect.
I see,
I created a new folder and set as 10G, unchecked " allocate max size..."
changed the coming schedule backup to this new created folder.
