Error in backup 0x807800C5

I had the same problem doing a System Image to a network share. I solved it and it now works after lots of research.. The following fixed my issue:

Turned all these 4 services to Automatic Startup:

-Microsoft Software Shadow Copy Provider

-Volume Shadow Copy

-Windows Backup

-Block Level Backup Engine Service

I also started them if they weren't running.

Used IP address instead of sharename when choosing the location of the network share. Ie type \192.168.0.10\backupfolder rather than \SERVER\backupfolder

Emptied Recycle Bin, closed unnecessary running applications

Checked permissions on server backup folder. Some people recommended adding Everyone and giving them Full Control, but I didn't find this necessary. I checked that the System, Network and Administrators group (which I'm a member of) had Full Control.

Turned Power settings on both machines (local and network) to Never turn off.

Oh I also temporarily turned off File History.

Not sure which of these made the difference but try them all, it may work for you.

Note I did NOT disable my AV (AVG -Active, Defender and Malwarebytes also on system) or Firewall nor did I need to repartition my drives. Also I'm on Windows 10, so saying it doesn't work on Windows 10 is wrong.

Good luck!

Hi Lawrence, no worries at all.

It does seem that Windows 10 has caused lots of issues for various different features, I suppose it's to be expected with a new release though. No doubt things will get ironed out over time.

I am doing this on Windows Server, but I'm not using Powershell, batch script or the command line directly. I'm doing this through Task Scheduler, and as the wbadmin command still exists in Windows 10, it should work with Windows 10 also.

I will guide you through what I have done, but on a Windows 10 PC:

1. Go to Start, type "Task Scheduler" and press Enter.

2. On the left, right-click on the item called **"Task Scheduler Library"**and click "New Folder...". Name the new folder something like "My Backup" so you can identify it later.

3. Right-click your new folder and click "Create Task...".

4. On the "General" tab, name the task something you'll recognise if you need to change it later. Select "Run whether user is logged on or not", tick the option to "Run with highest privileges" and to make it "Hidden". Also, on the general tab, you may need to change the "Configure for:" item to "Windows 10". 

5. Go to the "Triggers" tab and click "New...". Here, select when you would like to run the task. I have mine setup as a "Daily" occurrence running when my computer will be on, but not being used (e.g 03:00 am).

6. Go to the "Conditions" tab. If you have a laptop, you may want to "Start the task only if the computer is on AC power". the settings on this tab are really down to what kind of device you are using and how you want to configure it. Whatever you do, try to keep it simple!

7. Got to the "Settings" tab and tick, "Allow task to be run on demand", "Run task as soon as possible after a scheduled start is missed", "Stop the task if it runs longer than: 3 days", "If the running task does not end when requested, force it to stop". You can alter these selections if you wish, these are the settings I generally use.

8. Go to the "Actions" tab and click "New...". Leave the Action as "Start a Program", in the "Program/Script" text box, type: "wbadmin" (no quotes). in the "Add arguments" text box, type: "start backup -backupTarget:(Your Backup Drive, e.g E:) -allCritical -include:(Files to be included in the backup, e.g C:,E:) -quiet". Change the items in brackets to actual file paths/locations on your computer. Here's an example if needed:

start backup - backupTarget:\192.168.1.3\BackupFolder -allCritical -inlcude:C:\Users,E:\ -quiet

After this has been done, click "OK" on both windows you have open. A new task should appear in the middle pane in Task Scheduler. To test it, right-click the task and click "Run". You can view the history of each task by clicking on the task and then clicking the "History" tab on the lower-middle pane of the Task Scheduler. Here you can see whether the task has been started/completed successfully or not.

Hi !

Backup to NAS from Windows 8 works ( at least to Synology DS1813+ ) IF and AFTER:

 - disable SMB2 and large packets in Synology

 - edit smb.conf and ADD “strict allocate = yes” to all Shares !!!

After that also Windows 2012 can backup to NAS !!

Hope it helps,

So Neuigkeiten:

Also das Problem ist das SIe keine NAS-SERVER untersützten, ich soll nun einen Fall an Microsoft schreiben, und dann sehen wir mal was die Herrschaften dazu antworten.

Geht wohl wirklich um Sicherheitsprobleme oder der NAS ist einfach zu alt, díes könnte ebenso realistisch sein laut Kundenservice!

Ich werde den LINK vom Forum später hier posten!

News:

So the problem is that they do not support NAS SERVER, I will now write a case to Microsoft, and we'll see what the gentlemen respond to.

Goes really well to security problems or NAS is simply too old, this could be both realistic loud Customer!

I will later post the LINK from the forum here!

I had the same issue with my synology disk station. For me the following solution was helpful:

 

Perform System File Check (SFC), and then check if this fixes the issue.

Follow the steps:

a.       Press “Windows Key + Q” to open Charms Bar.

b.      Type “cmd” without quotes in the search box.

c.       On the left pane, right click on the “cmd” option and select “Run as Administrator”.

d.      Type “sfc /scannow” without quotes and hit enter.

Note: It may ask for windows installation DVD to fix and to enable SFC to make more than minor repairs. Some files saved on your computer might get deleted when fixing corrupted files.

Leider unter WIN 8 nicht so anwendbar!

Unfortunately, not to use under WIN8.
