Hello,
I got Comodo Backup up and running, and seemed to be doing well after a few hours, when I somehow managed to crash my machine (doing something unrelated) - when I booted back up, and tried to run another backup, as soon as I clicked the “Next” after the screen with the checkbox for scheduling a backup… It popped up a dialog saying: “An error occurred during the backup process.” - and the log said: “Error occurred. Could not retrieve disk signature.” and the next line: “Backup process failed with code 101450”
I quit and re-booted my system, and tried to run the backup again, and it appeared to start, and I left it alone, until the next morning. When I checked it, the log said that about 1 hour after I’d started it, it again failed with that error code. I forget if it said anything else specifically (like the signature bit above) - and it seems the log file is permanently set to overwrite all the time. No option to append or rename or anything like that…(?)
I’ll try another reboot and re-start to see if I can get it going again, and maybe I’ll get lucky and it’ll go all the way through. (few hundred gigs with compression turned on - it was estimating I think about 6 or 7 hours)
Info:
- v2.2.127000.12
- Windows Vista Ultimate 64bit
- Default region stuff, looking, it says Formats and Current location USA, and Language for non-Unicode programs is English (Canada) - and I am in Canada.
- My drive is an LG GSA-H22L but there’s no disk in it, and I wasn’t attempting to use it during the backup.
- I wasn’t running any backup or emulators during the backup that I’m aware of - I was only using Firfox v3.x
- Settings are: no auto check for updates, Enabled log, no password, log file:
K:\COMODO Backup\cbu_log.txt and backup source was “Disk, Partitions and MBR” with Disk0 “D:\ (XP32)” selected, Compression level “Medium” and Split Backup set to 1088MB and Destination was:
G:\COMODO_BAK\C_SYS_Part\Win32_XP.cbu - nothing else changed in Step 4 “Other Settings” and nor was “Scheduled Backup” checked. - Steps to reproduce are as above, basically just run Comodo backup, select to do a backup with settings as per 6. above, and just click “Next” to execute after the “Scheduled Backup” checkbox screen.
I think that about covers it - except that the partition I’m trying to backup is internal (Drive0, as indicated above) but the destination drive (G:) is an external USB drive.
As I say, I’ll try a reboot and try again, and let you know if all goes well (in 7 hours or so, if it does…) but once it gives that error, simply quitting and re-trying seem to just repeatedly give the error right away (when clicking “Next” to execute the job after the “Scheduled Backup” checkbox screen)
Thanks! 
Edit: Oh, but one thing: The “Diagnose / Repair” button always seems to just say: “The application is installed correctly!”
