What's new in SEP sesam 4.4.3 Grolar
SEP sesam new release, a hybrid Grolar, brings a fistful of features that may help improve protecting data in your environment and ease administrative tasks.
Version 4.4.3 Grolar introduces new S3 cloud storage to be able to safely store and retrieve your business data. Also new is enhanced capability to utilize NetApp hardware storage snapshots for backup.
SEP sesam no longer supports Hyper-V multiple virtual machine backup (by specifying all as a source) in one backup task. You have to configure a backup task for each virtual machine. Now it is also possible to restore single items from a Hyper-V backup.
New backup levels are available for Citrix XenServer backups.
SEP sesam allows administrators to configure access control lists (ACLs) for locations and clients, if they are granted appropriate permissions.
Direct access recovery (DAR) is now enabled by default during NDMP backup to enable selective restore. Previous special configuration of DAR is no longer required nor supported.
With Self-Service Restore Assistant you can now restore a data from a regular Path, NDMP and NSS backups as well as email(s) from Kopano backup.
Default access mode is now changed from CTRL to SM_SSH to provide more secure communication.
You can now exclude patterns (directories or files) from BSR image backup (BSR Pro 2.0) and activate compression. For details, see SEP sesam BSR Pro – Backup Configuration.
GUI enhancements enable you to check the Si3 deduplication store state, set your preferred GUI mode, clear the GUI cache memory, disable a particular backup task or a task group from running for a certain period of time, and set additional options.
Rythm templates can be used for customized advanced reporting. They are installed in the
<SESAM_BIN>/skel/templates/rythm directory. Note, however, that such custom reports are beyond the scope of SEP sesam standard support; they require additional technical assistance provided by SEP Consulting Service.
SEP sesam Server requirements
- JavaFX is required for the web dashboard and user-defined schedules. For details on the exact version, see Java Compatibility Matrix.
- 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.
Installation and upgrades
| As of Grolar release, SEP sesam executables are single signed with SHA256. Because of the buffer limitation of the GetCertHash() function on Windows Server 2008 SP2, the SEP sesam executables which are now signed with a SHA256 certificate cannot run on Windows Server 2008. To install/upgrade SEP sesam on the respective Windows Server version, you have to install a special Windows update first. For details and update download, see any of the following links:
SEP sesam Server and Client components should be upgraded to the latest version during the upgrade process. This ensures that SEP sesam Clients are fully protected. Customers with a valid license are eligible for a free upgrade of SEP sesam to any new release for the duration of the license. See also Automatic Updates and Automatic Installation on Windows.
Known issues and limitations
|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 Grolar known issues
- SEP sesam backup for hypervisors (VMware, Hyper-V, Citrix XEN, KVM, OpenNebula) cannot back up the data on the independent disks or Raw Device Mapping (RDM) disks
- When backing up via hypervisor and using external disk, SEP sesam cannot back up the data on the independent or RDM disks due to a hypervisor limitation that does not support including independent disks in virtual machine snapshots. The data of such disks is silently skipped from backup, hence the backup saveset contains no data for the independent disk while the backup succeeds and no warning about the missing data is issued.
- VMware does not support including independent disks in VM snapshots. As of Grolar version, SEP sesam issues a warning about the missing data for VMware. To avoid the warnings and have a successful backup, the independent disks and RDMs have to be excluded from the backup task or (see next item)
- To back up virtual machines that contain independent independent disks and RDMs, you have to install the SEP sesam Client in the virtual machine and perform an additional file or application backup to back up this data.
|If a restore of a VM with independent disk is performed to the original VM by using the option overwrite, the independent disk is re-created and all existing data on the restore target is lost.|
Enhancements and changes
S3 cloud storage
An S3 (simple storage solution) cloud storage can now be used to safely store and retrieve your business data. SEP sesam treats the S3 cloud storage like any other devices. It creates the snapshots and synchronizes data to the cloud. For details, see S3 Cloud Storage Backup.
NetApp storage snapshots
SEP sesam provides backup and restore integration built on NetApp Snapshot copies. You need to configure a new data store type – NetApp Snap Store to easily use hardware snapshots as usual backups. For details, see NetApp Storage Snapshots Backup.
Hyper-V backup and restore
- Separate task for each VM
- It is no longer possible to back up multiple VMs running on a Hyper-V with a single task. Now you have to create a separate task for each VM running on a Hyper-V standalone server or Hyper-V cluster. However, you can assign individual backup tasks to a task group and then trigger the backup of all tasks belonging to that group with a single event. For details, see Hyper-V Backup.
- Single item restore for Hyper-V
- Now you can restore single items from a Hyper-V backup if the saveset is stored on a data store. For details, see Hyper-V Restore.
Citrix XenServer new backup levels
Access control lists (ACLs)
The administrators can configure ACLs to enable or disable access to location (group of clients) or specific client. Note that before configuring ACLs, database-based authentication must be activated and users configured and added to the relevant group. For details, see Using Access Control Lists.
NDMP direct access recovery (DAR)
Direct access recovery (DAR) index is required to restore a directory or a single file from a NDMP backup (selective restore). As of version 4.4.3 Grolar, DAR is enabled by default (no configuration is required). While DAR can greatly reduce the time it takes to restore individual files, it might be unnecessary in case you want to backup and consequently restore only the whole volume. In such case, you may disable DAR to improve backup performance. For details, see NDMP Backup.
Self-Service Restore Assistant
It is now possible to use web restore assistant to restore data not only from regular Path backups, but also from NDMP and NSS file system Path backups as well as emails from Kopano backups with a few simple steps. You can connect to web restore assistant and perform a restore if you have appropriate permissions. If a backup is encrypted and the password is not stored in the SEP sesam database, it is now possible to enter the encryption password online. For details, see Self-Service Restore Assistant.
New default access mode
The default access mode is now SM_SSH (previously CTRL) which provides strong authentication and secured data communication for clients and servers in the SEP sesam environment. SSL libraries now iclude libmicrohttpd, libcurl, and libopenssl.
- SEP sesam introduces a number of data store enhancements (S3 credentials tab, Si3 State tab, new data store type, etc.). For details, see Configuring a Data Store and Configuring Si3 Deduplication Store.
- Database-based authentication and authorization are extended and can be combined with the LDAP authentication and authorization and/or with AD (Active Directory). SEP sesam authorizes the users based on the mapped roles and their associated privileges.
- SEP sesam features a GUI that can be customized and now also adjusted by selecting one of the following UI modes: basic, advanced or expert. The mode can be changed in GUI: from the menu bar select Configuration -> Defaults -> Extras -> UI Mode. For details, see UI Mode.
- A force refresh can be used to clear the GUI cache memory and consequently to update the view. For details, see All Results by State.
- Rather than deactivating a schedule (and all related jobs), you can now deactivate a single task but keep it in the list of tasks. You can also disable a whole task group by using the same option the Execution is blocked. You can enable a disabled task and/or task group again at any time. For details, see Disabling and Enabling Backup Task.
Changes in SEP sesam License
- New license editions VM Essential and VM Essential Plus introduce a CPU socket based license for VMware and Hyper-V backup.
- New license for 'source Side Deduplication'
