Backup file size
IN BE2014 ,I set the storage limit to 20GB and disabled preallocate disl space to maximum file size. there are two files servers in my backup job.
Don't know why the first backup files was not reach maximum size , only few GBs or hundreds MBs. And then BE created another .bkf.
In BE2010, we didn't have this issue and the foregoing .bkf files were all backup to 20GB before creating the next one.
- From BE 2012, when each resource is backed up, a new .bkf file will be used. This cannot be changed.
