Hello. I am currently using the Paragon Hard Disk Manager 14 Professional Demo. My intention is to buy it after I confirm that it works effectively to create incremental backups of various hard disks I have. The problem is this: it is taking forever to do an initial backup of a large drive. I have a 2 TB HDD, with approximately 1.5 TB of used space. I am trying to back it up to another 2 TB HDD in the same JBOD (connected to the computer by a USB 3.0 cable). After 12 hours, it says it still has 16 more hours to go. By contrast, if I do a "normal" PBF backup, it takes a maximum of (I'm estimating) around 10 hours. Here's another wrinkle: when I backup the C drive, which is about 66 GB of used space, it completes in about 7 minutes. What is going on? Why is it so slow? Do you have any suggestions? I want to use pVHD because I want to create quicker and more efficient incremental backups. Any advice would be appreciated. I am on Windows 7 x64. Thank you. EDIT: As a little update, it seems to be going about 10 MB/s (e.g. after a second or so, the filesize of the pvhd jumps from 858,132,600 KB to 858,142,600 KB). EDIT 2: In the end, it took around 60 hours! Crazy.
In case anyone is interested, I discovered how to solve the problem. Instead of writing to one large file, I had it split the image into separate files (the default was to create 4 GB-sized files, and I stuck with that). It ended up taking 6 hours, which is awesome. I am now quite pleased.
So, it seems to me that you got 40% less time that your expectation, or about 73 MB/sec average in a combined read/write operation. Do you attribute this to the pVHD format?
Robin, I'm sorry I haven't checked this thread since my last post. In case you remain curious, yes, I definitely attribute the faster speed to the pVHD (I believe it was also advertised as such, which is why I was so keen on trying it). I highly recommend it!
