I have Win 7 Home Premium SP1.
For the past year and a half, I've been using the Win 7 backup about once a month without any problems. My hard drive is partitioned into drives C and D, and I back up onto an external hard disk, which appears as Drive I when connected. (The external hard disk is partitioned into drives G, H, I, but there is plenty of space on drive I).
In addition, more often, I back up my important data folders (using MS Synctoy) on a USB flash memory which appears as Drive F. Yesterday, I backed up to the flash memory. Then I did the Win 7 backup to my external hard disc, but I forgot to remove the flash memory from the USB port, which I always do.
When the Win 7 backup finished, I got an error message from Windows Backup: "Windows Backup did not complete successfully. The backup completed but some files were skipped."
When I looked at "View Skipped Files", it said "Windows Backup skipped F:\Music because it cannot be found on drive F:\." (There is no "Music folder on drive F)
So I took out the USB flash memory and tried Win 7 Backup again (twice). Same result. Then I shut down the PC for the night. This morning I turned it on again. Everything else seemed to be working. So I did Win 7 Backup with the same result.
I looked at "Restore all users' files" in the Backup Window, and there I see that I have only a folder called "Users" backed up from the C Drive, and only a folder called "Music" backed up from the D Drive. I have many other folders in these drives, and even these folders only show a small portion of the files in those folders on my PC. It also shows that there is an empty F:\Music folder backed up. Just to remind you - there is no F Drive once I remove my USB flash memory.
Looking at "Manage Windows Backup Space" I see that on Drive I (the backup drive) I use 26.6 GB for Data File Backup, 95 GB for System Image, with 64 GB of free space on the drive. Since my C and D drives have a total of 74 GB used space, and I assume Win 7 Backup compresses files, these numbers look reasonable to me.
Can anyone tell me what's going on? Are my files backed up or not? Why the silly error message? My external hard disk seems fine, as best as I can tell
