Beefalo V2 SP2: Fixed issues
Kernel
SEP sesam v. 4.4.3.84 – Hyper-V restore with relocation may overwrite the original VM
Problem
The previous SP 1 (Beefalo V2 4.4.3.84) introduced a critical issue which is solved with SP2: Hyper-V restore of a virtual machine to a different location with a new name may overwrite the original VM, resulting in complete loss of data stored on the original VM. This only happens if the original VM is offline (powered off) at the time of a restore. This issue only applies if you are running SP 1 (4.4.3.84).
Workaround
Do not perform a Hyper-V VM relocation restore with SEP sesam Beefalo V2 SP1 (4.4.3.84).
Cause
The clustered=... information is stored as part of the source; this leads to misinterpreted relocation pattern during the restore and may result in the original offline VM being overwritten.
Hyper-V VM complete restore finishes successfully but VM is not recovered
Problem
The previous SP 1 (Beefalo V2 4.4.3.84) introduced a Hyper-V VM clustered restore issue which is solved with SP2: Hyper-V VM complete restore finishes successfully but some directories are not recovered and the VM does not exist in the Hyper-V Manager.
Cause
The clustered property was not set in the Hyper-V Failover Cluster Manager.
EOL of several media is extended by 3 days if a media timeout is set
Problem
The EOL of several media is extended by 3 days if a media timeout is set and there is no media in drive.
Cause
The initialization of a tape medium is retried even if the media load timeout has been reached.
Hyper-V VM selective restore fails with Failed to find parent file ...q-debian7_1VHD_0.vhdx
Problem
Hyper-V VM selective restore fails with the following error:
Hyper-V VM selective restore fails with Unexpected error: Failed to find parent file "C:\ClusterStorage\Volume1\Q-DEBIAN7_1VHD\DISKS\Q-DEBIAN7_1VHD\q-debian7_1VHD_0.vhdx". in the collection.
Cause
The problem with the temporary folder __DISKS__ which may contain images from the previous operation, resulting in the incorrect directory structure.
The VMDK mount operation is aborted
Problem
The VMDK (sm_vmdk_interface) mount operation is aborted after several minutes.
Cause
The sm_vmdk_interface does not wait until VMDKs become online.
Mounting VMDKs with the same file name on different data stores causes conflict
Problem
There is a problem with mounting VMDKs if VMDKs on different data stores (or folders) have the same file name.
Cause
The data store name is missing in the VMDK path.
Restoring Oracle controlfile from AUTOBACKUP fails with error
Problem
Restoring Oracle controlfile from AUTOBACKUP fails with: no AUTOBACKUP found or specified handle is not a valid copy or piece.

Path restore of a Hyper-V VHDX disk fails with "No entries found in LIS for..."
Problem
Hyper-V VHDX restore into the file system (path restore) fails with the error "No entries found in LIS for...".
Cause
In the SEP sesam GUI Hyper-V VM selection view it is possible to select the VHDX for restore instead of exploring it and restoring a file.
Service pack Client/GUI update may fail with error
Problem
Service pack update of the GUI package may fail with an error due to using sm_glbv.
Cause
SP update uses sm_glbv which is not present on the Client and GUI systems.
Data restored from BF64-encrypted savesets is not decrypted
Problem
There is a problem with the data restored from the BF64-encrypted savesets as the files are not decrypted.
Cause
Wrong encryption password was used during the backup.

Cause
The BF CPIO header check is missing.
Kopano public folder backup does not delete dump files
Problem
If a Kopano public folder backup is configured, the backup process fails to remove the dump files.

Problem
The .ini file in the Si3 deduplication store on the RDS contains the S3 credentials in plain text and everyone has read permissions.
Cause
The S3 access key is not encrypted.
VMware backup fails with IndexError: list index out of range
Problem
VMware backup fails with the IndexError: list index out of range in the sm_reformat_lis.
Cause
The NOT log (backup log file) is missing.
The sm_auto_conf_hw creates a core dump
Problem

Cause
Remote installation of SP does on Windows does not wait until the extraction is finished and ends with error.
GUI
GUI server fails to start with > version 11 OpenJDK
Problem
GUI server fails to start with Java runtime > version 11 as the data base access components do not load correctly, resulting in empty SEP sesam database.
Cause
GUI server won't start as it is unable to access the database.
Incorrect Path task type is set for Oracle
Problem
When creating an Oracle backup task and selecting the source, the task type is set to Path instead of Oracle.
Cause
The Oracle backup source tree is incorrectly placed under All local file systems.
Sending emails not possible when using the company official certificate
Problem
When changing the SSL certificate used by SEP sesam REST services to the company official certificate, it is no longer possible to send emails.
Cause
The HTTPS certificate file is a Windows file (\r\n line endings); the certificate fails to decode as the surrounding markers are not removed correctly.
Problem with AD/LDAP users in subgroups
Problem
AD/LDAP users in subgroups (nested groups) are not recognized by SEP sesam and cannot log in to SEP sesam.
Cause
The user roles are not correctly returned by the LDAP server (the server is not sending the required attributes).
Time frame selection in restore wizard does not work
Problem
The time frame selection (Saved in period option) in restore wizard does not work correctly.
Cause
The date converter does not correctly convert the dates with just one digit for the day.
Beefalo V2 SP1: Features
Hyper-V clustered VM is restored as clustered (by default)
Hyper-V clustered VM is restored as clustered by default. This setting can be switched off in the restore wizard.
By default, when the clustered VM is restored to the original Hyper-V server, it is restored as clustered to the node that owns it. The restore process recreates the VM with the original name and sets the property clustered=yes in the Hyper-V Failover Cluster Manager.
Beefalo V2 SP1: Fixed issues
Kernel
Remote command hangs if one line is too long
Problem
Remote command hangs if a line from the remote program is longer than 16382 bytes.
Backup to tape fails on Linux
Problem
On some Linux systems, a backup to tape fails because of unsupported read block size - errno EBUSY.
Mounting a VM with multiple disks on Linux
Problem
Mounting a VM with multiple disks on Linux mounts only one disk or fails to mount completely.
vSphere restore fails with vmx path has no extension
Problem
vSphere restore fails with vmx path has no extension when the VM name is too long.
Cause

VM backup with integer VM name fails
Problem
VM backup with integer VM name fails with ../sbccom.py", line 134, in closejob: cannot concatenate str and int objects (especially on Proxmox VE and OpenNebula).
Cause
The problem occurred with the backup sources (VM names) that consisted of numbers only.
Restore read size issue with LTO 7/LTO 8
Problem
The restore fails if the SMS data server does not reset a block size to the variable block size after write operation with LTO 7/LTO 8.
Cause
The restore read size is incorrect. Consequently, 2 blocks are read in one read operation. Setting a variable block size for LTO drives resolves the problem.
Selective restore on Windows restores wrong files or fails with the MTF error
Problem
Selective restore of a Windows saveset may restore wrong files or it may fail with MTF error due to ESET after a new segment (mainly on the RDX drives).
Cause
SSET generated false offset2 for ESET.

Problem
The sm_config_hw changes the device name of tape drive to a wrong value.
