3 disk is just 1% fragmented.
1% is very low. No issues there.
In dos mode it took 35 mins to complete backup for about 18GB of data.
Again, 35 min for 18GB is really very slow. However, I have never tried Paragons native boot environment for a BACKUP. I use it only for RESTORE so I can't comment on backup times using that method.
I ALWAYS create an image from within Windows using Paragons "Hot Processing" option because this allows me to continue using my PC even while the imaging is underway.
7 in windows, I wanted to check the integrity of the backup. So I tried rescue option from paragon and it said it couldn't load the backup due to it being complex or something.
TBH, I have never bothered to check image file integrity simply because I have the "Control Archive Integrity" option set to ON (IIRC, its the default setting) in Paragon and it does it for me automatically. From the Paragon B&R Manual -
"Control archive integrity. Mark the checkbox to guarantee that all backup images created with the program are 100 percent flawless. If you decided not to control the archive integrity, the backup operation would take about 3-5% less time."
I have been imaging and restoring using Paragon for years. Never checked integrity separately, never had a restore error. Ever.
Regarding your second point, I can see the problem but please note that what I am writing below is from personal experience and I don't think its documented anywhere.
When you create your image you have an (unsaid) "option" of creating a "simple" archive (say one drive, C:\ partition only) or a "complex" one, which includes things like the MBR area, Extended partitions etc.
If you click on the "root" in the "What to Backup" screen, you are in fact creating a "complex" archive image as you are automatically including the MBR and all available partitions.
Unfortunately, Paragon doesn't warn you about this. I learned this purely from personal experience having used this software for years now.
I believe the reason a "Complex Archives" cant be checked for Integrity in the normal way is because they in fact contain MULTIPLE partitions, the MBR area etc.
You don't need to bother with this option at all. Just create a "Simple Archive" by selecting ONLY the Partition/Drive you want to image and NOT the root, MBR area etc. If you create the image this way I'm fairly certain you can check image integrity later on but to be honest, I have never bothered with doing so as I have full faith in the default "Control Archive Integrity" option.
So it can't even load its own rescue media. Seems poorly written for a backup software.
Like I said above, thats because you made a "complex" image. I have restored my Paragon Images for years now, across several different types of drives of varying capacity. It works flawlessly though I do agree with you that the manual should be a bit clearer on certain issues.
If you guys have such good backup time, the only conclusion I can come to is the company devs have purposely reduced the speed in free version in latest release so that people buy their standard or pro versions.
Here's the thing - I have NEVER, EVER, used the paid version. I have always used the FREE version. I do however agree that you have spent way too much time on trying to get Paragon to work. For some reason its not working for you like it should. If you like, you can consider this app as well -

The "free" version pretty much does what you need but I personally prefer Paragon over it any day. If you have a Seagate drive, you can also try this option -

which is actually Acronis tailored specifically for Seagate drives. Again, 100% free...
