I am trying to find a free backup solution to backup a GFI MailArchiver server that will reside on a Windows Server 2012 R2 physical server. I bought a 5Tb Seagate Backup Plus drive, and was thinking of using Windows Server 2012 native backup solution to conduct image backups. However, we are looking at 200Gb+ of mail archive data not including the OS. I could see an image backup over the weekend, but then again I believe Windows Backup software will use the whole drive, and not allow other data to reside on the drive for nightly file backups, etc. I am not sure Windows Server 2012 is the best solution at the moment. Still exploring other free alternatives.
I wanted to use Seagate's DiskDrive software which has a limited version of Acronis that only does image backups, so this software is no different if it will work on Windows Server OS. This software was designed for Windows desktops, but it might work for a server. Seagate stated it may work, but its not supported.
Basically what I am wanting to do is conduct an image backup Sunday nights, and then a nightly file backup of the new GFI binary files including that active binary file that GFI Mailarchiver is archiving mail to. I would like to keep the most recent image backup intact in the event there is a problem trying to complete a new image backup. What I am saying is the existing sole image backup should not be over written without first ensuring the existing backup completes without error.
Please keep in mind this server solely functions as a mail archive server (GFI Mail Archiver 2013), and uses SQL Express to manage the binary files. GFI stores the actual mail message and attachments within the binary files, and sql express simply manages it. GFI is able to reconstruct everything solely using the binary files. I am not sure how that works since I have never had to resort to a full disaster recovery of this server.
Do you guys have any suggestions and/or alternatives?
