Error code 11'863'304 (0xB50508)

Dear communty,

I'll try first to open a support request, but not working anyway, still getting error on posting order code...

So I'll explain my issue there.

We are using "Synology" rackstation 407 & 409RP+ as backup destination for our servers. Everything was fine till we update the synology firmware to dsm 3.0 and later.

I'm getting this error code only on Windows 2008 Terminal Server. I really think that is something about credentials or rights, because on other servers (domain controller, exchange, database) where they use "DOMAIN\Administrator" account, everything is fine.

I know that the issue is more likely due to synology update, but I try the Acronis support too, because synology support send my there...

So I'll explain all the facts.

On Acronis B & R 10 (build 11696 or latest), I create my Backup Vault, giving UNC path like \\mybackupdest\myshare. Sometime I can sucessfully enter credentials, sometimes, it don't work. Even if I can "map/create" my vault, when the scheduled backup task starts, it gives me the mentionned error message.

Here's the full error message from one of our Terminal Server :

Task 'Incremental backup' failed: 'Error occurred while running the backup and recovery engine.

Hope someone can help me.

Thanks by advance.

In addition to this, I've been trying to backup using "FTP" protocol. So I activate the ftp service on my backup destination and try to backup to ftp site using valid credentials. This works perfectly except that the archive files are splitted to 2Gb, which become non-understandable to perform restores or following backup evolution statistics.

Hope this help.

Thanks by advance.

Best Regards
