Is one of the server's disks full or nearing its capacity?
0x80070008 means "Not enough storage is available to process this command."
This message does not always indicate a lack of disk space, but that is the
first thing to check if you get it.
Tip: to quickly translate a Windows error code like 0x80070008 to a readable
message, take the lower half - the last 4 digits, in this case 0008, convert it
from hexadecimal to decimal - in this case 8, and then pass that value after
'net helpmsg ' at a command prompt.
Works for most error codes, up to a decimal value of a few hundreds.
C:\>net helpmsg 8
Not enough storage is available to process this command.
Some other common ones:
C:\>net helpmsg 3
The system cannot find the path specified.
C:\>net helpmsg 5
Access is denied.
The upper part - 0x8007 - gives info about where the error originated, and the
sort of message (first digit 8 or C = error), but there's no such way to
quickly decode it at a command prompt.

Subject: [Bacula-users] Shadow Copy issue - Fatal error: VssOject is NULL
I have been running the same version of Bacula on a Windows 2k12 server for
over a year (5.2.10). A few weeks ago, we started getting all our jobs failing
over the weekend due to an apparent issue with VSS. Has anyone encountered the
following fatal error:
20-Apr 19:30 bacula-zha JobId 5546: Start Backup JobId 5546,
Job=Software_Share_Backup_-_Encrypted.2015-04-20_19.30.00_41
20-Apr 19:30 bacula-zha JobId 5546: Using Device "FileStorage-software" to
write.
20-Apr 19:30 bacula-zha JobId 5546: Sending Accurate information.
20-Apr 19:30 bacula-sd JobId 5546: Volume "zha-software-encrypted-vol0360"
previously written, moving to end of data.
20-Apr 19:30 bacula-sd JobId 5546: Ready to append to end of Volume
"zha-software-encrypted-vol0360" size=1775302040
20-Apr 19:30 fs01 JobId 5546: Fatal error: VSS API failure calling
"CoInitialize". ERR=Unexpected error. The error code is logged in the error log
file.
20-Apr 19:30 fs01 JobId 5546: Fatal error: VSS was not initialized properly.
ERR=Cannot create a file when that file already exists.
20-Apr 19:30 fs01 JobId 5546: Fatal error: VssOject is NULL.
20-Apr 19:30 bacula-sd JobId 5546: Elapsed time=00:00:06, Transfer rate=0
Bytes/second
20-Apr 19:30 bacula-zha JobId 5546: Error: Bacula bacula-zha 5.2.13 (19Jan13):
The only way to "fix" this is to reboot the client. Items I have tried:
* Restarted the Bacula service on the client - backups still failed
* Tested connection to client using the 'estimate' command, success. Issue
isolated to Windows server.
* List current VSS instances via cmd prompt (vssadmin list writers) - All
states reported as Stable / No writers reporting errors
* Manually create a shadow copy on the client (vssadmin create shadow /for=e: )
and then manually remove all shadow copies (vssadmin delete shadows /all) -
backup still fails
* Ran System File Checker (sfc /scannow) - No issues found, backups still fail
After rebooting the client, backups using VSS work fine for a few days and then
start failing with the same FATAL error. It is not always the same job that
fails first.
On the client, these entries are logged in C:\Program
Files\Bacula\working\zhfs01.trace
fs01: vss_generic.cpp:366-0 VSSClientGeneric::Initialize: CoInitialize
returned 0x80070008
If anyone has any ideas on how to further troubleshoot this issue, or have
encountered this before, I'd greatly appreciate it.[/img]
