What's new in SEP sesam v. 4.4.3 Tigon

SEP sesam new release, a hybrid Tigon, brings a fistful of features that may help improve protecting data in your environment and ease administrative tasks.

Version 4.4.3 Tigon introduces new KVM-related backup extension that is already a part of a SEP sesam Tigon client. It provides efficient data protection for libvirt-based KVM virtualization.

A new extension is included for online backup of SAP ASE based on Sybase database.

SEP sesam supports automatic backup for newly added VMware virtual machines (VMs).

Windows Server 2016 is fully supported with a new version of the disaster recovery solution SEP sesam BSR Pro 2.0 for Windows.

SSL certificates are used to enhance security and help strengthen data protection by providing a secure connection for data transfer to and from SEP sesam Remote Device Server (RDS).

Si3 encryption can be defined on the Si3 deduplication store level. The Si3 deduplication store can now be used for initial seeding.

SEP sesam NDMP now supports single file restore from dump backups with selective restore and allows to exclude certain files from backups.

RHV VM restore introduces VM reduction by creating a thin-provisioned disk file.

GUI enhancements enable you to set database-based authentication and set the default data size units.

If SEP sesam Server is running, the REST API can be accessed via the base URL: http://<host>:<port>/sep/api/. For details, see Using SEP sesam REST API.

SEP sesam Server requirements

Java 8 (at least patch level 111)
SEP sesam Tigon v. 2 requires Java version equal to or higher than JRE 8u111 (≥ JRE 1.8.0_111). regardless of the operating system. Previous Tigon versions also require Java 8 for Windows Server and GUI, but not for other OS. For details, see Java Compatibility Matrix.
JavaFX
JavaFX is required for the web dashboard and user-defined schedules features. The dashboard can also be viewed in GUI, but only if JavaFX is present on the respective GUI client. If JavaFX is not available, the web dashboard can only be accessed by browser (http://[servername]:11401/sep/ui).
Information sign.png Note
Oracle®'s Java 8 already includes JavaFX (e.g., on Windows). Oracle®'s OpenJFX Project provides JavaFX packages that can be installed separately if some other Java version is used, such as IBM Java, which is typically installed on SuSE. Depending on your system and Java version, manually install either OpenJFX package or Oracle®'s Java 8 on your SEP sesam GUI client to have all the latest features available.
64-bit or PowerPC (PPC) architecture required
SEP sesam Server requires an operating system running on 64-bit or a PowerPC (PPC) architecture. PowerPC (PPC) is supported for several Linux distributions, see SEP sesam Support Matrix.

For details, see SEP sesam Support Matrix and SEP sesam Server hardware requirements.

Previous release

Known issues and limitations

Information sign.png Note
Antivirus programs may disrupt network communication and cause SEP sesam processes, such as backup and replication, to fail. One program that is known to cause SEP sesam processes to terminate is Sophos Firewall with IPS (Intrusion Prevention System) enabled. Make sure that there are no antivirus, firewall, IDS or IPS programs preventing interaction with SEP sesam.
4.4.3 Tigon known issues:
SEP sesam ≤ 4.4.3.45 – Migration ignores client defined by migration schedule/event
  • In SEP sesam versions equal to or lesser than 4.4.3.45, if you select a client as a migration source in the schedule/event rather than in migration task, the data is not migrated because SEP sesam erroneously ignores the client.
Workaround: To select a client as a migration source, specify the client when creating a migration task: Main Selection -> Tasks -> Migration tasks. For details, see Creating a migration task.
SEP sesam Lotus Notes Linux sbc < 4.4.3.45 – Exclude pattern with leading \. does not work
  • In SEP sesam versions lesser than 4.4.3.45, the exclude list, defined on Linux/UNIX in a Lotus Notes backup task, does not work if specified with \..
Workaround: For SEP sesam versions < 4.4.3.45, specify the exclude list for Notes without the preceding backslash and a dot, e.g., use /srv/notesdata/help$ instead of \./srv/notesdata/help$'.
SEP sesam sbc Windows from 4.4.3 to 4.4.3.42 – A UNC path backup silently excludes files without file extension
  • As of SEP sesam v. 4.4.3, if the backup source of the UNC path backup is set at the top level to //server/share, e.g., //myserver/users, files without file extension are silently excluded from backup. Even though no exclude is defined, they are excluded because the source //server/share is extended with wildcard *.*, which is checked for regular files as of sbc Windows 4.4.3. This issue only occurs if the source is set at the top level; if the source is defined at the lower level, e.g., //myserver/users/anonymus, all files are backed up normally.
Workaround: When backing up a network share and your source is set at the top level, use the wildcard * to process all regular files: //server/share/*; e.g., //myserver/users/*. SEP support is working on this issue and will provide an sbc patch as soon as possible.
Resolve: Fixed with a hotfix available for x64 and x86 Windows versions under https://download.sepusa.com/servicepacks/4.4.3_Tigon/4.4.3.39/hotfix/ with description: A UNC path backup silently excludes files without file extension (includes previous 4.4.3.39 patches).
Linux
SEP sesam unable to start necessary amount of processes since Systemd 228:
Resolve: Resolved with entry TasksMax set to infinity in configuration file /lib/systemd/system/sepsesam.service.
SEP sesam version 4.4.3.42 – Starting Si3 deduplication server fails
  • In SEP sesam 4.4.3.42, starting Si3 deduplication server fails with the following error: Starting dedup sever fails with java.lang.VerifyError: Uninitialized object exists on backward branch 209.
Resolve: This issue occurs if the installed Java version is not supported. SEP sesam requests a Java version equal to or higher than JRE 8u111 (≥ JRE 1.8.0_111). For details, see Java Compatibility Matrix.
SEP sesam version 4.4.3.42 – Windows
IBM Domino Server aborts when starting INCR backup but 'ARCHIVE' logging style is not enabled:
  • In SEP sesam 4.4.3.42, when running IBM Domino INCR backup but 'ARCHIVE' logging style is not enabled then the Domino Server aborts.
Resolve: Call NotesTerm() in that case. Hotfix for SEP sesam clients or servers, available at https://download.sepusa.com/servicepacks/4.4.3_Tigon/4.4.3.39/hotfix/sbc_lotus_notes_fe36fab_x64_win-4.4.3.39.exe.
SEP sesam version 4.4.3.39/.42 MaxDB backup fails
  • In SEP sesam 4.4.3.39/.42 MaxDB/SapDB backup ends with ssb-error.
Resolve: Fixed with a hotfix, available at https://download.sepusa.com/servicepacks/4.4.3_Tigon/4.4.3.39/hotfix/ssb_33d5536_x64_win-4.4.3.39.exe.
SEP sesam version 4.4.3.39/.42 - Setting the Client filter in 'All Results' throws Java Lang NPE
  • In SEP sesam 4.4.3.39/.42 - Setting the Client filter to a specific name in the status view 'All Results' aborts the GUI with a Java Lang Null Pointer Exception.
Workaround: Do not use the Client filter in status view 'All Results'.
SEP sesam version 4.4.3.39/.42 - Changing the default interface in a drive group restarts the drives
  • In SEP sesam 4.4.3.39/.42 - Changing the default interface in a drive group restarts the drive configuration for all drives connected to same Server or RDS.
Workaround: Do not change the default interface of a drive group unless all drives are idle.
SEP sesam version 4.4.3.39/.42 – Log files in SMS directory grow too large
  • In SEP sesam 4.4.3.39, the sm_dedup_fsck log file in the <SESAM_VAR>/var/log/sms is growing too fast and is too large. This can cause performance issues and consume valuable disk space.
Workaround: There are two possible solutions:
  1. Stop SEP sesam and delete all files from the <SESAM_VAR>/var/log/sms.
  2. To prevent the logs to become that big in the future, edit the file \var\ini\sm_sdslog.xml. Go to the section
<appender name="FSCK" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <file>${gv_rw_stpd}/sm_dedup_fsck-${drive_num}.log</file>
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
      <fileNamePattern>${gv_rw_stpd}/sm_dedup_fsck-${drive_num}_%d{yyyy-MM-dd}-%i.log</fileNamePattern> 
and change .log to log.gz at the end of the last line:
     <fileNamePattern>${gv_rw_stpd}/sm_dedup_fsck-${drive_num}_%d{yyyy-MM-dd}-%i.log.gz</fileNamePattern>
SEP support is working on this issue and will provide a fix as soon as possible.
Fixed with SEP sesam Server version 4.4.3.42 Tigon:
SEP sesam version 4.4.3.39 – Microsoft SQL Server backup with source '{instance}/{database}' fails
  • In SEP sesam 4.4.3.39, you cannot use backup sources with '{instance}/{database}' for Microsoft SQL Server backup tasks; backup with exclude file fails with error: Could not find DB with <...> name.
Workaround: Use backup source 'all'.
Resolve: Fixed with a hotfix for SEP sesam clients or servers, available at https://download.sepusa.com/servicepacks/4.4.3_Tigon/4.4.3.39/hotfix/sbc_45bd78f_x64_win-4.4.3.39.exe.
SEP sesam version 4.4.3.39 – VSS Hyper-V backup fails
  • In SEP sesam 4.4.3.39, VSS Hyper-V backup fails with error: Virtual machine is located on CSV and non-CSV volumes.
Resolve: Fixed with a hotfix, available at https://download.sepusa.com/servicepacks/4.4.3_Tigon/4.4.3.39/hotfix/.
SEP sesam version 4.4.3.39 – IBM Domino differential backup fails
  • In SEP sesam 4.4.3.39, when running IBM Domino backup and a database is not accessible, the following error occurs: File is not a database; consequently, backup fails.
Resolve: Handling of NotesTerm() and NotesInit() is improved with a hotfix for SEP sesam clients or servers, available at https://download.sepusa.com/servicepacks/4.4.3_Tigon/4.4.3.39/hotfix/sbc_lotus_notes_fe36fab_x64_win-4.4.3.39.exe.
SEP sesam version 4.4.3.39 – Tape encryption is set, but no longer recognized
  • In SEP sesam 4.4.3.39, if media property of an encrypted tape was modified in GUI, SEP sesam incorrectly interprets its encryption flags; consequently, the encryption is no longer recognized.
Resolve: SEP support is working on this issue and will provide a fix as soon as possible.
SEP sesam version 4.4.3.39 – Restore fails when selected save set contains umlauts or Unicode characters
  • In SEP sesam 4.4.3.39, when a selected save set for restore contains umlauts or Unicode characters, GUI cannot find matching LIS line because UTF-8 character encoding was not preserved. Consequently, restore fails.
Resolve: Fixed with a hotfix. You can download the sm_ui.jar from https://download.sepusa.com/servicepacks/4.4.3_Tigon/4.4.3.39/hotfix/gui/sm_ui.jar into <SESAM_BIN>/bin/gui folder on SEP sesam Server. Then restart the SEP sesam UI server by running sm_main reload rmi.
SEP sesam version 4.4.3.39 – Selective restore becomes full in case of a vSphere Server client
  • In SEP sesam 4.4.3.39, GUI starts selective restore of a single file as full if the target client is a vSphere Server.
Resolve: Download sm_ui.jar (GUI patch for v. 4.4.3), available at https://download.sepusa.com/servicepacks/4.4.3_Tigon/4.4.3.39/hotfix/.
SEP sesam version 4.4.3.39 – Saveset EOL is automatically adjusted and may result in over-increased EOL
  • In SEP sesam 4.4.3.39, a Saveset EOL is automatically adjusted for:
    • DIFF/INCR backups and migrations, when a save set belonging to a FDI chain has too short EOL; if such a save set is missing in the target pool, then any consecutive DIFF/INCR backup or migration that is running on a pool with longer EOL will increase the EOL of the save set from the respective pool.
    • Failed backups and migrations; this results in extended EOL of the previous successful backup, either a COPY backup or complete FDI chain.
  • In such cases, the EOL of a save set stored on another pool is automatically extended. In the case of migration of DIFF/INCR save sets (when a save set belonging to the FDI chain is missing in the migration pool), this may lead to excessive EOL prolongation for save sets that originally have a very short EOL. For example, because DIFF/INCR migration detects that a save set belonging to the FDI backup chain is missing in the migration media pool, the EOL of the save set in the original pool is automatically extended, e.g., DAY (EOL: 5) to EOL of YEAR (EOL: 375).
Resolve: Fixed with a hotfix, available at https://download.sepusa.com/servicepacks/4.4.3_Tigon/4.4.3.39/hotfix/. It prevents automatic EOL adjustment in the case of DIFF/INCR save sets migration. In other two cases (DIFF/INCR backups and failed backups and migrations), the automatic EOL adjustment works as expected and cannot be switched off; for details, see Managing EOL.
SEP sesam version 4.4.3.39 – VSS Hyper-V restore fails
  • In SEP sesam 4.4.3.39, Hyper-V restore fails with error: Call Detect() is failed for file descriptor.
Resolve: Fixed with a hotfix, available at https://download.sepusa.com/servicepacks/4.4.3_Tigon/4.4.3.39/hotfix/.
SEP sesam version 4.4.3.39 – Hyper-V restore does not support target volume different than source volume
  • In SEP sesam 4.4.3.39, you can only restore Hyper-V VM to the same target volume as the source volume.
Workaround: Restore a VM to the original location as described in Hyper-V Restore. SEP support is working on this issue and will provide a fix as soon as possible.
SEP sesam version 4.4.3.39 – the GUI on SEP sesam Linux Server does not allow to change media properties
  • In SEP sesam version 4.4.3.39, the GUI on Linux SEP sesam Server throws an exception when changing media properties.
Resolve: Fixed with a hotfix. You can download the sm_ui.jar from https://download.sepusa.com/servicepacks/4.4.3_Tigon/4.4.3.39/hotfix/gui/sm_ui.jar into <SESAM_BIN>/bin/gui folder on SEP sesam Server. Then restart the SEP sesam UI server by running sm_main reload rmi. SEP sesam Clients can be updated the next time they connect to the server. For automatic client updates, see Using sm_update_client for automatic updates.
