Hi, We’re about to implement Veeam Backup for Microsoft365 (VBO on premises), we already have VBR. We want this M365 backups to go to tape drives (regulatory requirements) so we were thinking on having a repository that is shared accross VBO and VBR, where we deposit VBO backup files, that is readable from VBR to do file to tape jobs. Is it possible? do you have a better architecture?

Hi Community.  I am unable to resolve the above referenced issue.  This happened after an update to v13.  After the install, it worked for 2-3 days. I then started to configure my tape infrastructure and when I finished, I was prompted to reboot the server.  Now I can’t get back into the console.  Any help would be greatly appreciated.

Simple question, but I don’t think this is possible from reading up about this, there is a great video on migrating, but I think this assumes you still have the old VMWare infrastructure as well as your destination Hyper-V. So, the question is then, can you restore a full backup of a VMWare VM, onto Hyper-V? Assume pre-reqs like removing vmware tools are taken care of, but the actual conversion to Hyper-V can this be done without running your source VMW environment?

VB365 Exchange Online backup is failing for 1 mailbox out of 600. Initially received EWS ErrorMailboxStoreUnavailable (“The mailbox database is temporarily unavailable. Cannot open mailbox”). After reruns, 2 affected mailboxes succeeded but 1 mailbox continues to fail with HTTP 403 Forbidden.The O365 team confirmed the user account is disabled, the Exchange license has been removed and the mailbox was converted to a shared mailbox.Has anyone seen this behavior with recently converted shared mailboxes? Can VB365 back up an unlicensed shared mailbox or are there specific mailbox attributes that should be verified? VB0365 Exchange Online backup is failing for 1 mailbox out of 600.

Hi guys, Yesterday we attempted to upgrade our VBR server from V12.3.2.4465 to V13.0.2.29 but were met with the below error during the installation process -  The upgrade failed and did not allow us to retry at all. Certain options were greyed out - Checking Apps and Features, Veeam reported that it was upgraded but the app was inaccessible. -   In the end, we were forced to back out of out upgrade.Has anyone seen this before? ShaunB.

I currently have a Veeam Backup & Replication v12 environment running on Windows Server. I have acquired a new server and plan to migrate my backup infrastructure to Veeam Software Appliance (VSA) v13 in order to benefit from immutability and the enhanced security features provided by the appliance.I would appreciate it if you could share your experience and best practices regarding this migration.Specifically, I am looking for guidance on the recommended procedure to migrate from Veeam Backup & Replication v12 on Windows Server to Veeam Software Appliance (VSA) v13, while preserving existing backup jobs, repositories, configuration, and historical backups.Any feedback, lessons learned, or official migration steps would be greatly appreciated.Thank you in advance for your support.

hello, i am running veeam agent 13 standalone free editon, the latest version. i know it is the latest version, as about dialog box shows that.i getting the following error and i do know understand what the exact issue is?please, my first question is did veeam actually complete the backup?this has been going on for several weeks.the full backup is done each week and it completes without error.what does `Agent failed to process method {Signature.FullRecheckBackup}` means and perhaps how to fix it?the destination is a smb share on a synology device. tho, in this case, as mentioned, the client is running standalone veeam agent 13note: that same synology device, has been a backup repository for veeam backup and replication for many years, never had any issues. thanks much, david   

Hi everyone,I updated Veeam B&R to version 12.3.2.4854 following a known security issue.After the update, all jobs no longer start automatically, even though they are correctly scheduled.Even new jobs don't start automatically.If started manually, the jobs run correctly.All Veeam services are up and running correctly.Could anyone give me some advice on how to resolve this?Thanks to anyone who can help.

Hi. I have a mid-range gaming PC. It has a 1 terabyte internal SSD. 510 gigs are used, of which Steam games are 230 gigs (easily redownloadable), hyberfil.sys is 13 gigs, pagefile.sys is 8 gigs and my VRChat cache is 32 gigs (easily rebuildable). Experiments have shown that this filesystem, when these items are excluded, compresses to 185 gigs and that an incremental each day comes to about 20 gigabytes.I have a 1 terabyte external disk drive that I want to leave permanently plugged in. Obviously I’d like to keep as many days’ backup as possible, while allowing for reliable backup.What settings do people suggest I use?  Keep backups for _ days, and in the Advanced tab, what should I put for: Synthetic full backup, Active full backup, Defrag and compact full backup file. For the advanced tab, I don’t quite understand them. 

Hello everyone,I updated a VBR console to v13, but after the update, I was unable to connect to the console and received the following message:“Failed to connect to the backup server: Access to the registry key ‘HKEY_LOCAL_MACHINE\SOFTWARE\Veeam\Veeam Backup and Replication\Plugins’ is denied”I noticed that when I launch the console using “Run as administrator,” I can access it without any issues. I checked the Registry Editor, and the permissions are correct.What’s surprising is that I haven’t encountered this error with other customers who have upgraded to v13.I don’t know how to resolve this issue. Do you have any ideas, or have you also experienced this problem?Thanks in advance  Bonjour tout le monde,J'ai passé une console VBR en v13, cependant après cette mise à jour je ne parvenais plus à me connecter à la console avec le message suivant:"Failed to connect to the backup server: Access to the registry key 'HKEY_LOCAL_MACHINE\SOFTWARE\Veeam\Veeam Backup and Replication\Plugins' is

Hi,We have a client which has Veeam Windows Agent free edition version 13 installed. The agent back up to a local USB disk. Now the client would like to have a second job to back up to our Veeam Cloud Connect console.However we still have VSPC version 8.1.0.21999 installed and our Cloud Connect Server is at level 12.3.3I know ideally we should upgrade our infrastructure to version 13 and also the VSPC console. Question is: Is it possible to add the client with the new Windows agent to our VSPC without needing to downgrade the Window agent? Ideally I’d like to install the management agent to the client laptop and use the already installed Windows agent which converts to a license version and install the second job to back up to the data center.I don’t like the idea to upgrade the infrastructure in a rush for that client.Thanks,

They want a detailed description but truncate it at about 2.000 characters :("Provide a detailed issue description and error messages." field does not accept more than that.Usually I prepare my issues in text editor and in the end copy/paste into support portal.Now I realize only half of it made it through while I don't have my original any more.I'd expect the GUI at least to give a warning. Noone serious will type his message into some web form initially and realize the input no longer works as he’s typing live.Who can fix that? Open a case for it? ;)
