kg512 Posted August 10, 2010 Report Share Posted August 10, 2010 I'm trying to backup a client's computer via a multiserver, open file backup license v7.7. It's a mixed enviornment of Windows 7, Vista, XP. This client's computer is the only Windows 7 computer on the network. When doing a backup, I get the following: T-14: VssWSnapVolume: DoSnapshotSet failed, winerr -2147212513, error -3045 Can't use Open File Backup option for OS (C:) on Dell, error -3045 ( there is insufficient storage space to complete the operation) There is 45.5GB (out of 97) free on the source drive, and 3TB available on the destination drive. Upon checking the event viewer, I have this error: Volume Shadow Copy Service error: Unexpected error querying for the IVssWriterCallback interface. hr = 0x80070005, Access is denied. . This is often caused by incorrect security settings in either the writer or requestor process. Operation: Gathering Writer Data Context: Writer Class Id: {e8132975-6f93-4464-a53e-1050253ae220} Writer Name: System Writer Writer Instance ID: {320cb735-d289-48be-9689-7a8cf5c865e0} It seemes like a security issue? maybe? I've tried changing the logon settings for the VSS service, but that created "unknown Windows OS error." Can someone help me out with this?

Lennart_T Posted August 11, 2010 Report Share Posted August 11, 2010 When using Backup Open Files, Retrospect stores files on the client's boot hard drive. The boot drive is normally C:, but there is no guarantee. So, how much free space is there on the client's boot drive? Have you tried running CHKDSK on the client's boot drive?

kg512 Posted August 11, 2010 Author Report Share Posted August 11, 2010 Thank You for responding! We have 45.5GB free (out of 97GB total) on C: chkdsk did find errors so I tried another backup, but received the same errors. Quote Link to comment Share on other sites More sharing options...

We have 45.5GB free (out of 97GB total) on C: chkdsk did find errors so I tried another backup, but received the same errors. The free space should be enough (assuming that C: is indeed the boot drive). Now, was CHKDSK able to correct the errors? Quote Link to comment Share on other sites More sharing options...
kg512 Posted August 12, 2010 Author Report Share Posted August 12, 2010 c: is indeed the boot drive, and chkdsk did fix the errors. But still unable to use open file backup. Quote Link to comment Share on other sites More sharing options...
Lennart_T Posted August 13, 2010 Report Share Posted August 13, 2010 Then I'm out of ideas. Sorry. This forum is only user-to-user. You might want to contact Retrospect Support Quote Link to comment Share on other sites More sharing options...
jgowing Posted August 24, 2010 Report Share Posted August 24, 2010 Hi Katie, I suspect you may have a permissions issue. Sounds like you are backing up clients from a server. You dont mention whether you have a domain or not. Retrospect runs on the backup srver either under the System Account or as a specific user as determined in COnfig>Prefs>Security So I supect that this user may not have permissions on your clients. If you have a domain I suggest creating a special user for retrospect, give it at least backup operator permissions, if not admin. If no domain you may need use a common machine administrator account, or create a common account on all the clients. See the Manual >Ch1 > Creaating Retro user Account and Ch9 > Administratin > Preferences > Security for more on this HTH Quote Link to comment Share on other sites More sharing options...
