BE 2010 R3 : Backup files take much more space than the actual backuped files !
We use BackupExec 2010 R3 (under W2008R2) to backup data from a Windows 2008R2 file server, and an Exchange 2007 server.
The storage space for backup files is located on the backup server itself. This space is also used for other backups (not through BackupExec, but using SFTP on Unix servers).
Our Windows file server holds about 2,7 TB of data (and not all is backuped).
On our backup server, the *.bkf files related to our file server take an amount of 3,48 TB ! According to the modification date of these *.bkf files, they are all actively used.
It seems that BackupExec expands the size of the backup files until it reaches the total available space on the device. Due to this, the other SFTP backups don't work properly.
Is there a way to avoid such behaviour of BackupExec 2010 R3, forcing it not to exceed a specified amount of disk space ?
Thanks for reading, have a nice day
