I have always done a Full Backup onAcronis and have restored dozens of full backups with no problems.

I decided to try a Differential backup.
What I did was remove a couple of folders and then add a new folder and then do a Differential backup.I noticed that on my differentiak backup that the two removed folders and the new folder was also there as expected.

On looking for help on restoring a differential th Acronis help is very vague.My question is to do a full restore do I use the differential first and then the fullbackup,or do I just use the differential or do I use the Full backup only as it is not clear in Help file.Finally will a full restore put back the 2 folders I removed and the new folder.I personally think it will and if it does then it is useless and I will have to go back to full backups only. Your remarks appreciated.

You will need the original Full backup and the latest Differential. Start the Restore with the Differential first.

I have never had to use it, but I have my full Backup and weekly Differentials. I delete earlier differentials as they are not needed (unlike Incrementals, which are all needed for a Restore).

As you say, the instructions are not particularly clear, but the above is how I 'see' it.

Thanks for your time Technotiger I will use the differential first and then the full backup to do a full restore. But as you say it is a bit hit and miss as I feel that when you do a full restore this way it will put the folders you have removed back onto the system which you do not want. I feel that sticking to full backups is the only way you can get a full system that you want. It probably okay for file only restores.

I mostly use the clone feature which I assume is a full backup? (After a scan for virus and malware, and a defrag). I am not sure if the differential back up is different to a cloned disc.

A differential backup, only updates an Original backup, a Differential on its own is not a full backup.

A Clone backup in Acronis is a Full backup, and is mainly intended for when one wants to Restore the backup, to a Different Hard drive on the same PC - as in the case of a hard drive failure.

I found a very good guide to installing & using Acronis Tru Image here :- click here it is also down loadable in PDF form. There is also a very good guide to automatic back up using TI here :- click here

I tend to avoid incremental or differential backups, and only do a full system backup each time. It takes a little longer, but I think it's worth it from the security aspect. I just feel that the more bits and pieces you have to reassemble in order to gain a full up-to-date image, the more risk there is.

But I expect that view will get shot down!

I keep three full backups on my external drive at any one time. Whenever I've created a new one, I then delete the oldest.

I do as Pineman. I have just reformatted my main PC and reinstalled every programmme. (it zooms along now).
Prior to any major programme installation I do a complete image backup. I find that it takes less than ten minutes to create an image including verification. I currently have four images covering the latest installations.
