{note:title=Important Upgrade Considerations}

When users who have environments with Debian (deb) packages upgrade the Data Center Console, the system displays a message similar to the following:
{code}Configuration file `/usr/sbin/r1soft-datacenter-console/conf/server.properties'
==> Modified (by you or by a script) since installation.
==> Package distributor has shipped an updated version.
What would you like to do about it?{code}
*All DCC data is overwritten and lost* if you respond by pressing "Y" or "I." The default action keeps your current version. This issue does not affect environments using RPM packages.

h2. NEW FEATURES

h4. SBM 5.10.0


h5. Site to Site Replication

New configuration options and internal changes are provided to support policy based site to site replication of server backups to additional SBM servers. This new feature provides a simple means to replicate backup data across SBM servers regardless of their physical location. While this feature does not support synchronization of multi-tenant accounts or server configuration, replicated SBM server data can be used to restore an SBM server. Another nice feature of our SBM Site to Site replication is that you can actually restore data to a server downline from your SBM replica. Data is transferred securely over SSL channels. Replication of data can be enable or disabled at the Disk Safe level.

h5. Product Re-branding

In alignment with recent changes, references to “Idera” have been removed from the interface.

h5. Improved Filesystem Support for ext4 with 64bit Feature

The ext4 filesystem support has been expanded to support the 64bit Feature found in modern Linux distributions. This change applies to both the Server Backup Manager and its agents.

h5. File Download Logging

File downloads from recovery points are now logged as an event. Additionally, downloads are prevented when the Server Backup Manager is in Maintenance Mode

h5. Persistent Maintenance Mode

When Maintenance Mode is enabled, it will remain enabled after server restarts.

h5. Agent Log Downloads from SBM

In the Servers listing, an new action icon has been added to fetch the log files from any of configured servers. You can specify the download path on the SBM server in the "Configuration > Manager Options" interface.

h5. Tuning Options for h2 Internal Database

The h2 database is used internally by the SBM to record configuration information and activity records. SBM now offers improved tuning options to control its runtime characteristics. The new tuning options can be set in /usr/sbin/r1soft/conf/h2.properties. The options are:

* *CACHE_SIZE (default value: 16384)*
** {color:#333333}The database keeps most frequently used data in the main memory. The amount of memory used for caching can be changed using the setting {color}CACHE_SIZE. The value of CACHE_SIZE is specified in kilobytes.
* *DEFAULT_LOCK_TIMEOUT (default value: 60000)*
** {color:#333333}The number of milliseconds until a lock timeout exception is thrown.{color}
* *LARGE_RESULT_BUFFER_SIZE (default value: 4096)*
** {color:#333333}The buffer size for large result sets. The value of LARGE_RESULT_BUFFER_SIZE is specified in kilobytes. Set this value to 0 to disable the buffer.{color}
* *LOCK_TIMEOUT (default value: 60000)*
** {color:#333333}The number of milliseconds until a lock timeout exception is thrown. The initial lock timeout for new connections is set by DEFAULT_LOCK_TIMEOUT.{color}
* *QUERY_CACHE_SIZE (default value: 8)*
** {color:#333333}The size of the query cache, in number of cached statements. Each session has it's own cache with the given size. The cache is only used if the SQL statement and all parameters match. Only the last returned result per query is cached.{color}

h2. FIXED ISSUES


h3. SBM 5.10.0

* Addressed a timeout issue which may result in failed replication of recovery points. This issue would be seen associated with an error message of "Could not read from socket: null"
* DCC user filters were not working as intended.
* SBM to DCC policy syncing was not reliable.

h2. KNOWN ISSUES

h5. Common Problems and Issues

* MSSQL database detection shows an error, but database backups are successful.
* Multipath I/O storage configurations are not tested and have been found to not function in some configurations.

* Users who have more than 1,500 mount points per device may experience performance issues during a file restore or when attempting to browse recovery and archive points.
* When using the API  you must designate the type of user on the "user=" line, as either--user=dcc/someuser
or
\--user=sbm/someuser
Otherwise, the user defaults to local users.
* *{_}If your Windows environment contains an MSSQL or Exchange database on two different partitions{_}*, you should enable multi-volume snapshot (MVS) in the policy settings.

h5. Installation issues

* Server Backup 5.2.x and later do not support remote deployment to a Windows 2003 server because installing drivers requires user interaction.
* Users who attempt to install Server Backup Manager on a Microsoft Windows 2003 operating system must note that .NET 2.x or 3.5 is required. .NET 4.0 does not satisfy this requirement. When installing SBM on Windows 2003, the installer fails if the proper .NET version is not installed. Note that the installer does not prompt you to install the correct .NET version before failing.
* The temporary (.tmp) folder is not deleted after completing a silent install of Server Backup Manager or Backup Agent using the default values. The folder is empty, but still exists on the server.

h5. Restore issues

* Users who use Centos LiveCD on any bare-metal restores that have LVM may receive error messages that they failed to restore deltas to a certain device number. This issue results from the fact that because the Centos LiveCD uses its own LVM to manage its file systems, dm-0 and dm-1 are always in use. To avoid this issue, choose a target that is two LVM devices higher than the original. For example, if /tmp is originally on /dev/dm-1, you should choose /dev/dm-3 as your target.
* RecoveryCD versions 4.2.0 and 5.0.0 do not work when performing a bare-metal restore to a target that includes mdadm and LVM devices.
* Some users may receive an exception error message when attempting to exclude a large group of files in a directory when performing a restore.
* Microsoft Exchange Server 2007 users cannot restore a mailbox database to an alternate location.
* Some users may experience Java heap space out-of-memory error messages when attempting to restore a database with large LongBlob or LongText types.
* Disk safe verification verifies only those recovery points with an available status. DSV does not verify recovery points with a locked or incomplete status.

h5. Data Center Console issues

* The Data Center Console does not automatically restart after a new Windows installation.
* The Data Center Console displays incorrect values in the *Compression Type* section of the Edit Disk Safe window after editing the values.
* Internet Explorer users who enable the Compatibility view may notice graphical display issues when attempting to view some Data Center Console pages, such as the Disk Usage, Volumes, and Policies pages. This issue does not occur in other Web browsers.

h5. Parallels Virtuozzo user issues

* Not all files are downloaded for a container on Virtuozzo and system displays the error message, {{ERROR - Failed to download file}}, in the log file.
* Parallels Cloud Server 6.0 users may notice that Virtuozzo virtual machines are not detected as devices in the Disk Safe wizard. The VMs are backed up. If you need granular file restore for a VM, you can back up the PCS VM by installing a Server Backup Agent in the VM guest operating system
* Virtuozzo users may notice that when some containers are downloaded, the compressed file does not contain the first and last container listed in the recovery points.
