I'm a total newbie here but I did search for other threads on my problem and did not find anything exactly similar enough to match my needs. Sorry if this is in fact a duplicate post. Also, not as technical as many in this community so please explain real "simple like"
I have 2 computers; 1 desktop and 1 laptop. Both have Win 7 and Ghost 15 SP1 on them with 4 GB RAM.
The drive I backup both computers to is a USB drive hooked up to my desktop. My laptop I run through the network to that drive via Wireless N+ Router
My desktop has had no problems whatsoever running full drive backups with automatic validation turned on, or associated incremental backups with validation from the time I bought the software (I switched from Acronis True Image Home about 2 months ago). It works perfectly with the USB Drive attached to the back.
The problems are backing up the laptop. On full drive backups only, with validation, I get the following errors 95% of the time when connected wirelessly. The drive is about 140GB
Error EC8F17B7: Cannot create recovery points for job: Drive Backup of OS (C:\), RECOVERY (D:\).
Error ED800012: The internal structure of the recovery point file (CRC Validation) is invalid, damaged or unsupported.
Error ED800012: The internal structure of the recovery point file (%1) is invalid, damaged or unsupported.

Incremental backups on the laptop to this drive, with validation on, have yet to give me a problem in the past couple months. They work just fine. The only time I get the error is on the full drive backups, done wirelessly. I decided to try tonight to hook the USB drive directly to the laptop and ran a full drive backup with validation turned on with no issues, so it does not appear to be a RAM or disk problem with either drive.
Can anyone suggest possible reasons or cures to this problem? I have not yet tried a full backup with throttling enabled, as I saw recommended on some threads. If I do, 1) What speed would you recommend and 2) what is the reasoning behind this solution? If throttling doesn't work, what would my next step be? Could it be a router setup issue? Do you think it is something else entirely?
As a side note, turning off validation is not an option even though that is what Norton Customer Service VEHEMENTLY said I should do. They said I would be fine so long as I manually did the validation after the backup, even though I didn't really even need to do that and could trust the backup to be fine so long as it completed successfully. 
. If I have to do it manually, what is the point of having a setting to do it automatically, please?
I would appreciate any help you could provide.
Thanks in advance,
Ross
