What's new in SEP sesam 4.4.3 Tigon v.2

SEP sesam 4.4.3 Tigon v.2 introduces new Kopano backup (previously Zarafa backup) and Self-Service Restore Assistant.

Tigon v.2 provides enhanced backup and restore capabilities for DB2 with DB2 automatic archive log backup, simplified backup and restore for SAP ASE, and restoring MS SQL database to a new location using GUI.

GUI enhancements enable you to clean up orphaned save sets from data store manually, quickly scan the success of backup jobs by toggle grouping, use improved smart grouping when generating a task for grouped VMs, and examine the progress of the replication.

The maximum initial size for Si3 deduplication store is restricted to 40 TB.

SEP sesam will automatically retain the last successful backup or migration save set in the same pool when the next backup/migration fails. Note that this behavior is version specific and it differs from the default behavior implemented in version 4.4.3.42 Tigon. For details, see Managing EOL.

SEP sesam Server requirements

Java 8 (at least patch level 111; note that Java 9 is not supported!)
SEP sesam 4.4.3 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 v.2 known issues:
SEP sesam v. 4.4.3.48 – Slow performance with Linux backup which uses Blowfish Encryption, *.lis files are missing
  • In SEP sesam version 4.4.3.48, backup on Linux/UNIX client which uses the Blowfish Encryption causes the entire backup process to slow down due to high STPD output logging which halts generation of *.lis files. SEP sesam uses the *.lis files to create information about the backup unique files, which are then used by the restore wizard, therefore any potential restore would be incomplete and data would be lost.
Workaround: Create a new set of backup tasks for your Linux/UNIX clients with Advanced Encryption Standard (AES) encryption. SEP support is working on this issue and will provide a STPD patch as soon as possible.
SEP sesam v. 4.4.3.48 – Hyper-V restore – import fails if only a Windows Client package is installed on the Hyper-V Server
  • In SEP sesam Windows Client package 4.4.3.48, a hyperv_import.dll is missing. Consequently, Hyper-V restore – import fails if only the SEP sesam Windows Client package is installed on the Hyper-V standalone server or on Hyper-V cluster nodes.
Workaround: Uninstall the SEP sesam Client package and install the SEP sesam Server package (includes the Client and GUI components) on your Hyper-V standalone server and, if clustered, on Hyper-V cluster nodes. For details, see Microsoft Windows installation.
SEP sesam v. 4.4.3.48 – Installation is aborted with a misleading error message
  • In SEP sesam version 4.4.3.48, Java 8 requirement is checked during installation. If the required Java version (at least patch level 111 ≥ JRE 1.8.0_111) is not present or the existing version is too low (e.g., Java 1.8.0_101), SEP sesam installation is aborted with an incorrect error message; instead of reporting that SEP sesam requires at least Java 1.8.0_111, a message similar to the following is shown: Unable to launch <path>sm_db_update.exe ...SetVDDK failed. sm_db_update.exe returned 2., and the installation is aborted.
Workaround: Make sure that you install the required Java version and repeat SEP sesam installation/update procedure. SEP support is working on this issue and will provide a fix as soon as possible.
SEP sesam v. 4.4.3.48 – The Loader content in GUI may show incorrect status
  • In SEP sesam version 4.4.3.48, the Loader content is not updated in GUI if only the slot content has been changed manually. The Loader content is only updated if a drive-related change was performed, such as unload or load. In case you have changed the content of your tape device manually and then performed archive adjustment by using the option Adjustment by barcode only (checking the barcodes of all tapes which are not in drives – without loading them into the drive and reading the label), the manually changed slot content is not recognized and the Loader content in GUI is not updated.
Workaround: SEP support is working on this issue and will provide a fix as soon as possible.
SEP sesam v. 4.4.3.48 – The data store cannot be deleted in SEP sesam GUI
  • In SEP sesam version 4.4.3.48, it is not possible to delete a data store via SEP sesam GUI even though the data store does not contain any valid or locked data.
Workaround: SEP support is working on this issue and will provide a fix as soon as possible.
Fixed with SEP sesam Server 4.4.3.48 Tigon V2:
SEP sesam version ≤ 4.4.3.45 – Throughput for local backups is very low
  • In some Linux systems, e.g., SLES 12, the local loopback device lo is often configured with MTU (Maximum Transmission Unit) size 65536 (64K). This may decrease the local transfer throughput because the MTU size is equal to the transfer buffer size used in SEP sesam.
SEP sesam v. 4.4.3.45 – Hyper-V backup of several VMs silently skips some VMs
  • While trying to backup multiple virtual machines, only the last VM is backed up. The other VMs are skipped. This happens because SEP sesam erroneously backs up only the last VM in the source list.
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.
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 \..
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.
Linux
SEP sesam unable to start necessary amount of processes since Systemd 228:
  • Linux: Since Systemd 228 and up from kernel 4.3 SEP sesam is not able to start more than 512 processes. The message "Resource temporarily unavailable" is visible in sm_qm_main log.
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.
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.
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.
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.
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.
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.

Enhancements and changes

Kopano backup

Zarafa re-branded to Kopano in 2016; SEP sesam provides efficient data protection for this mail and messaging collaboration suite in place of Zarafa. SEP sesam backup extension for Kopano Collaboration Platform provides backup and restore of single user mails, mailboxes and public folders. For details, see Kopano Backup.

Self-Service Restore Assistant

As of v. 4.4.3. Tigon v.2, it is possible to restore save sets online with the Self-Service Restore Assistant. After authentication users can restore their own data, if they belong to the user group restore and the following conditions are met: backed up data belongs to an ordinary Path backup (no special backup types, such as system state backup, SAP Hana, Exchange Server, can be restored online); if a backup is encrypted, the password must be stored in the SEP sesam database (SEP sesam does not provide an option to enter the encryption password online). For details, see Self-Service Restore Assistant.

Simplified SAP ASE backup and restore

The SAP ASE backup extension is now implemented as an internal backup appliance to provide efficient data protection for SAP ASE and simplify the restore process. It performs online backups of SAP based on Sybase ASE databases using the Sybase SQL API. For details, see SAP ASE Backup.

DB2 automatic archive log backup

In order to enable online backups of DB2, you have to enable archive logging for DB2 by modifying the LOGARCHMETH1 and LOGARCHOPT1 database configuration parameters. This enables automatic archive log backup to SEP sesam. For details, see DB2 Backup.

Restoring MS SQL database to a new location using GUI

SEP sesam GUI now provides a simple way of restoring a SQL Server database to the same machine while retaining the old one in place. This is an alternative to the move option which lets you define the new name of the database files as well as new location for these files. For details, see GUI restore wizard relocation.

GUI enhancements

  • You can manually remove orphaned save sets from the data stores by using the new Clean up option in the Data Stores content pane. This is useful in cases when a data store seems to be inaccessible, its storage space is occupied, or SEP sesam space check shows non-sesam data. For details, see Data Store.
  • You can use additional Toggle Grouping option in the Backups content pane to group the same backup task states in one item and display its current status. Grouping allows you to quickly scan the success of backup jobs. For details, see Toggle Grouping.
  • When automating backup of virtual machines by creating VMware tasks, you can use the improved Create VM tasks option with a powerful Attributes feature to enable smart grouping of existing or new VMs that fit certain criteria for backups. For details, see Automating Backup of Virtual Machines.
  • In the Migration and Replications content pane you can examine the progress of the replication and see how much data is being transferred; you can check data size, physical and nominal data in the new columns Data Size, Transferred, Transferred (Brutto) and Progress. For details, see Checking replication status.

Limited maximum initial size of Si3 deduplication store

To avoid issues arising from combination of too large Si3 deduplication stores and inefficient hardware, the maximum initial Si3 deduplication store size is restricted to 40 TB since Tigon V2 (4.4.3.46). This restriction is valid when creating a new Si3 deduplication store in GUI.

Information sign.png Note
Customers with special requirements for larger Si3 deduplication store should contact SEP support to be able to increase the value up to an optimum size for their specific environments.
