h1. {color:#172b4d}Known Issues{color}
{color:#000000}{*}Common Problems and Issues{*}{color}
* {color:#172b4d}When Disk Safes grow larger than 32TB, backups fail with : "reset(): database or disk is full", even when sufficient storage space is available.{color}
* {color:#172b4d}File search will run forever for protected machines with EFI partitions, the search will get stuck in /boot/efi. As a workaround, specify the starting path for the search.{color}
* {color:#172b4d}Multipath I/O storage configurations with duplicate device UUIDs are not supported and have been found to not function in some configurations.{color}
* {color:#172b4d}The merge task may fail when you attempt to merge a recovery point that was interrupted due to CLOB/BLOB issues. If the merge fails due to this issue, merge the points one by one. After the merge fails, merge each recovery point one by one until the task is successful.{color}
* {color:#172b4d}Users who have Debian installations should note that a Debian-based machine that has both RPM and DEB packages installed is recognized as RPM-based only by Server Backup Manager.{color}
* {color:#172b4d}Users cannot set heap memory for more than 1024 MB using {color}{color:#172b4d}{*}serverbackup-setup \-m{*}{color}{color:#172b4d}. Even if there is more than enough space, Server Backup Manager displays a message indicating that memory specified must be smaller than 1024 MB. Edit server.conf to update memory settings.{color}
* {color:#172b4d}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.{color}
* {color:#172b4d}(Cosmetic) zk-web messages in SBM log after install or upgrade. Steps to resolve can be found{color} {color:#172b4d}[here|kb3:zk-web messages in SBM log after install or upgrade]{color}
h5. {color:#172b4d}Installation issues{color}
* {color:#172b4d}Server Backup 5.2.x and later do not support remote deployment to a Windows 2003 server because installing drivers requires user interaction..{color}
h5. {color:#172b4d}Restore issues{color}
* {color:#172b4d}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 {color}{color:#172b4d}_/dev/dm-1{_}{color}{color:#172b4d}, you should choose {color}{color:#172b4d}_/dev/dm-3{_}{color}{color:#172b4d} as your target.{color}
* {color:#172b4d}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.{color}
* {color:#172b4d}Some users may receive an exception error message when attempting to exclude a large group of files in a directory when performing a restore.{color}
* {color:#172b4d}Microsoft Exchange Server 2007 users cannot restore a mailbox database to an alternate location.{color}
h5. Parallels Virtuozzo user issues
* {color:#172b4d}Not all files are downloaded for a container on Virtuozzo and system displays the error message, {color}{color:#172b4d}{{{}ERROR - Failed to download file{}}}{color}{color:#172b4d}, in the log file.{color}
* {color:#172b4d}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.{color}
* {color:#172b4d}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.{color}

h1. {color:#172b4d}Known Issues{color}
{color:#000000}{*}Common Problems and Issues{*}{color}
* {color:#172b4d}When Disk Safes grow larger than 32TB, backups fail with : "reset(): database or disk is full", even when sufficient storage space is available.{color}
* {color:#172b4d}File search will run forever for protected machines with EFI partitions, the search will get stuck in /boot/efi. As a workaround, specify the starting path for the search.{color}
* {color:#172b4d}Multipath I/O storage configurations with duplicate device UUIDs are not supported and have been found to not function in some configurations.{color}
* {color:#172b4d}The merge task may fail when you attempt to merge a recovery point that was interrupted due to CLOB/BLOB issues. If the merge fails due to this issue, merge the points one by one. After the merge fails, merge each recovery point one by one until the task is successful.{color}
* {color:#172b4d}Users who have Debian installations should note that a Debian-based machine that has both RPM and DEB packages installed is recognized as RPM-based only by Server Backup Manager.{color}
* {color:#172b4d}Users cannot set heap memory for more than 1024 MB using {color}{color:#172b4d}{*}serverbackup-setup \-m{*}{color}{color:#172b4d}. Even if there is more than enough space, Server Backup Manager displays a message indicating that memory specified must be smaller than 1024 MB. Edit server.conf to update memory settings.{color}
* {color:#172b4d}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.{color}
* {color:#172b4d}(Cosmetic) zk-web messages in SBM log after install or upgrade. Steps to resolve can be found{color} {color:#172b4d}[here|kb3:zk-web messages in SBM log after install or upgrade]{color}
h5. {color:#172b4d}Installation issues{color}
* {color:#172b4d}Server Backup 5.2.x and later do not support remote deployment to a Windows 2003 server because installing drivers requires user interaction..{color}
h5. {color:#172b4d}Restore issues{color}
* {color:#172b4d}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 {color}{color:#172b4d}_/dev/dm-1{_}{color}{color:#172b4d}, you should choose {color}{color:#172b4d}_/dev/dm-3{_}{color}{color:#172b4d} as your target.{color}
* {color:#172b4d}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.{color}
* {color:#172b4d}Some users may receive an exception error message when attempting to exclude a large group of files in a directory when performing a restore.{color}
* {color:#172b4d}Microsoft Exchange Server 2007 users cannot restore a mailbox database to an alternate location.{color}
h5. Parallels Virtuozzo user issues
* {color:#172b4d}Not all files are downloaded for a container on Virtuozzo and system displays the error message, {color}{color:#172b4d}{{{}ERROR - Failed to download file{}}}{color}{color:#172b4d}, in the log file.{color}
* {color:#172b4d}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.{color}
* {color:#172b4d}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.{color}
