Hello,
during a Backup, the following error occurs “Backup failed with code 180 (Item skipped)”.
I believe that this error is related to “Shadow Copy”.
Although in the settings I stated “Volume Shadow Copy”
( Backup Method —> When encountering locked files: Volume Shadow Copy ).
(:SAD) I have the same problem. I am using “Windows Vista Home Premium” and “Comodo Backup 4.3.5.2”. I did a “Full backup” of selected User files and selected the “Simple copy” option. I backed up to an External USB Hard Drive on an encrypted partition which I mounted beforehand using True Crypt. It was originally “Local Disk (F:)” before it was encrypted now when mounted it is “Local Disk (G:)”. As in Windows Explorer both F:\ and G:\ Drive showup but as in Windows Explorer F:\ drive is not accessible only G:\ drive. For some reason True Crypt needs F:\ drive reserved for encryption purposes as it said when it was encrypted F:\ drive can no longer be used. I believe the fact True Crypt encryption has been used and the whole F: vs G: drive thing has nothing to do with the issue I just mentioned it just for further information.
When I mount the drive I always mount it to G:\ drive and I checked the permissions used and they are the same as any other partition or external drive. I can copy and paste to the drive with no issue. Comodo backups to the drive with no problems until towards the end of the backup when it always gives the error code. I looked at the drive itself and after granting permission to the Administrator Account to view the files I see they have indeed been backed up. However Comodo Backup does not list any backups as having occurred. The only way I could restore files is by manually going to G: Drive, granting permission to the Administrator Account to access the files, and copy and pasting them over.
This would not be too bad, the problem is I have to do a Full Backup each time I backup this way. I can not create a Full Backup set and then using that backup set to create Differential and Incremental backups. I also can not automatically restore files to their original locations but would have to do so painstakingly manually to each and every folder and files that needed to be restored. Basically I might as well copy and paste entire folders over manually from G:\ drive. Comodo with the exception of making it easier to select what I want to backup does me little good due to this error not allowing the backup to register with Comodo as having completed successfully.
Besides the error after the backup finishes when I look in Manage it says the name of the Backup and says “was NOT backed up properly”.
I scanned the entire error log ion the screen when the last backup completed when I did a quick web browsers backup using the same settings as mentioned above. I got some files with “Error code 90” at the end. I am using the default setting “Volume Shadow Copy” which should eliminate such errors. Also I selected the option to “ignore read errors from source” on another scan and it made no difference. Finally for a troubleshooting test thinking “Error code 90” (90 = a file/folder is used by another program) was what was making the entire backup fail, I did a backup of just photos in the “Pictures” folder. Thinking since restarting I had not viewed them and no program should be accessing them it would be a good control test. Sure enough the backup completed successfully. It also showed up in “Restore” “Recent Backups” and in “Manage” as “successfully backed up”.
The problem is then likely with Volume Shadow Copy, related to “Error code 90”, and possibly “ignore read errors from source” option being ignored when selected.
When I did the backups the only thing running was Comodo Backup and Windows along with the background programs running none of which were running a scan or monitoring files. I even shut down all the background programs in the system tray and disabled real time protection on Microsoft Security Essentials. Still the full backup failed even though virtually all files copied over perfectly. Why can not Comodo make the backup succeed with a warning with dialog listing the files that failed to backup rather then having the whole backup fail. This way users can run a second backup catching what was missed without having an entire backup fail. Seems silly to loose an entire backup set because a few insignificant files failed to backup because another program was accessing them. Do I really care that a log file was not backed up? Even if the files are potentially important why let a few important files cause an entire backup set to fail? For example when I was using Firefox and ran a backup of user files some .sqlite and .db files got flagged with error code 90. These are important files if you need to restore a firefox profile for example, but all my favorites, documents, photos, movies, E-mail which I consider much more important was backed up. Why lose the ability to easily access them and restore them just because of the few failed .sqlite and .db files within the backup set?
Error code 90 means that the files is used by another program and it can’t be backed up using the standard method. This is what causes the error 180 (item skipped)
For Volume Shadow Copy to work properly you need to run the backup process as administrator . True Crypt has some limitations for Volume Shadow Copy service, see TrueCrypt
