I was pleased to see that Paragon Backup and Recovery 12 provides its own hot copy service rather than depending on VSS; something is knackered in VSS on my Windows 7 x64 system and Windows Backup has never worked properly either. So I managed to successfully create a 226 GB backup of my main hard drive partition, spanning some 59 files in 4 GB chunks. Unfortunately, I cannot check the archive's integrity without the program crashing once it reaches the file ending in .025 – the 38th file, 148 GB in. I get a Windows error dialog that says "A part of Paragon System Utilities has stopped working", with the following signature details: Code: Problem signature: Problem Event Name: APPCRASH Application Name: launcher.exe_Paragon System Utilities Application Version: 10.1.19.15839 Application Timestamp: 4ff4d00c Fault Module Name: hdm.dll Fault Module Version: 10.1.19.15839 Fault Module Timestamp: 4ff4caf5 Exception Code: c0000005 Exception Offset: 001b068a OS Version: 6.1.7601.2.1.0.768.3 Locale ID: 4105 Additional Information 1: 0a9e Additional Information 2: 0a9e372d3b4ad19135b953a78882e789 Additional Information 3: 0a9e Additional Information 4: 0a9e372d3b4ad19135b953a78882e789 I figured I would try posting here because it takes hours to keep trying to verify this backup and it would take additional hours to keep trying to re-create it, so if someone knows what is going on, that would be great. I'm going to try verifying it from the boot CD next. EDIT: When checking the archive integrity, the Linux-based boot CD appears to fail silently at exactly the same place! Is there something else I can do to get more verbose information?
