>>> Is DriveHQ a solution for Real-Time or daily backup of a SBS 2003 server Data with an Exchange Server ? The data change rarely (about 15 Gb) but the exchange server is about 15 Gb also). Is there tools available to avoid sending the whole Exchange server on a daily basis throught Internet ? <<<<
Yes, DriveHQ Online Backup 4.0 is an ideal solution for backing up servers.
By default, DriveHQ Online Backup 4.0 runs as a service and it can backup / protect your files even when nobody is logged on. It also supports incremental backup, so it only backs up files that were changed after the previous backup.
Please note real-time backup is good only for relatively small folder(s). If you have a very large folder (e.g. 5000 files / subfolders), please use daily or weekly backup.
It should have no problem backing up 15GB as many users have 100GB or more data. However, to backup SQL server or Exchange Server, it is recommended backing up locally before backing up to DriveHQ online storage. SQL server backup and Exchange server backup supports differential backup.
