Added a 1Tb secondary hard drive to the weather PC, this was bought from dabs.com and was delivered within a few days, I’ve always had excellent service from dabs.
The Dell Precision 490 has a spare bay for a hard drive but it needs a special caddy, these are less than £5 from Charles Computers on Ebay.
The fitting is really straightforward as all the required cables are pre-installed, once plugged up, the PC is turned on and as soon as the Dell logo is shown, pressing F2 enters the BIOS, here the SATA drive is enabled, before rebooting.
I’m using Acronis True Image 2015 and using the Tools>>Clone Disk option made the secondary drive bootable and also this will be where backups are stored.
I have set Acronis to generate ‘Version Chains’ it does this by making a full backup first and then differential backups, every fifth backup is a full one and the chain starts again, any version older than six months is deleted.
The Version chain is ran three times a week to the secondary drive with a full backup to an external drive being done weekly.
