Fixed issues

[ABR-234238] Agent for VMware: Service_process.exe may crash while performing a VM replication operation in unstable network environments.
[ABR-233514] Agent for VMware/Hyper-V: Running a virtual machine from a backup may fail with "Error code: 7 'Disk is not found." in some cases.
[ABR-233109] Agent for VMware: The backup of a ESXi host configuration to a location which contains spaces in its name fails with the "The archive is invalid or its type is unsupported" error.
[ABR-230924] Browsing a network share fails when performed by Agent for Linux or bootable media, if the password contains a comma symbol.
[ABR-229797] Agent for Exchange: The backup of an Exchange DAG instance may randomly fail with the "The process cannot access the file because another process has locked a portion of the file" Windows-specific error.
[ABR-228965] Agent for VMware: VMware ESXi VMs are not displayed in the Devices list, if these VMs have a specific text used in "Annotations" (starts with '<' symbol).
[ABR-222746] Browsing of a network share with the enabled SMB encryption fails when it is performed from the Acronis bootable media environment.
[ABR-222703] Acronis MMS service may crash and generate core dumps on the specific Linux distributions after installation of Agent for Linux.
[ABR-220046] A files/folders backup of an SMB share does not produce warnings about automatically skipped files/folders ( for example, skipped due to lack of access permissions).
[ABR-219758] Backup performance may become slower than expected if the archive is created in v12 (default) format and the archive size is more than ~5 TB.
[ABR-219577] Agent for Exchange: If the "Maximum Shadow Copy Storage space" limit is configured in the VSS settings, then this limit becomes "UNBOUNDED (100%)" after the backup of an Exchange database.
[ABR-219330] Agent for Linux: A backup of an XFS volume with minor AGFL corruption performed in the sector-by-sector mode if the volume resides on a drive with the 4K sector size.
[ABR-217457] Agent for Windows: The mms.log is spammed every 1 minute with "Error 0xfff0: The specified domain either does not exist or could not be contacted" if the machine is added to the domain, while "Acronis Managed Machine Service" (MMS) service is running under the local user account.
[ABR-216451] A backup plan with the enabled archive encryption in rare cases may produce non-encrypted backups which causes further incremental backups to fail with the "incorrect password" error.
[ABR-212285] If a backup was captured by Agent for Windows from a Windows machine which contains LDM volumes, then recovery (X2V) from this backup performed by Agent for VMware/Hyper-V (agent-less) may fail with the "Failed to copy the volume." error.
[ABR-203889] A backup into a huge archive located on the NTFS file system or SMB network share may fail with "Error occurred while backing up." and "ERROR_FILE_SYSTEM_LIMITATION (665)" errors when using the backup format v12.
Fix: the archive stored in the backup format v12 is now automatically split into 200 GB chunks when saved to an NTFS file system or SMB share.
[ABR-202625] When browsing an encrypted archive via Windows Explorer, the password for the archive is prompted only once. No prompt for password when an archive is closed and re-opened via Windows Explorer.
[ABR-202548] Agent for Linux: A differential backup of a Linux machine disks/volumes may be of the same size as a full backup in specific cases.
[ABR-200589] Agent for Linux: A backup of a Linux machine disks/volumes fails with "Internal error: record is greater then 32K" when the system contains lots of mount points ('cat /proc/mounts' exceeds 32K).
[ABR-199432] Backup plans do not run on schedule after changing the user under which the "Acronis Managed Machine Service" (MMS) service is running.
[ABR-197411] Agent for VMware: Virtual disk changes from the "Thin provisioning" to "Thick provisioning" mode after VM replication when the source VM disks are located on the NFS-backed datastore.
[ABR-194557] Agent for Hyper-V: A Hyper-V VM backup produces the following warning - "Changed Block Tracking (CBT) is not used because there are disk files that do not belong to any disk snapshot." - if there is a tree of Hyper-V VM checkpoints which includes two or more sibling checkpoints with no common parent.
[ABR-193871] Agent for Exchange: Unable to back up the same Exchange DAG database on two nodes simultaneously, the backup fails on one of the nodes.
[ABR-190721] Agent for VMware: The "The virtual machine may be backed up without using Changed Block Tracking (CBT) because the machine has snapshots." warning is shown after a backup in more cases than it should.
[ABR-173514] Agent for Hyper-V: A backup of a Hyper-V VM which contains shared VHDX disks may produce inconsistent backups.
[ABR-173114] Agent for Hyper-V: A backup of a Hyper-V VM may end with the "error 0x1403f4: WMI 'ExecQuery' failed for query '%ls'." warning in some cases when a Hyper-V host is under high load due to WMI unresponsiveness.
[ABR-169993] Agent for VMware: A backup of VMware VMs may fail with the "GXT: The item provider has skipped the report of an item with key '('[UUID]','mms::vm::datastore')'" error if there are VMs present in the vSphere infrastructure which have references (connected ISO images or virtual disks) to the inactive or previously deleted datastore in their configuration.
[ABR-160770] A files/folders recovery from a disk/volume archive is slower than a recovery from files/folders archive in the same backup location.
[ABR-152605] Agent for VMware: Presence of a broken/invalid datastore in the VMware vSphere infrastructure makes Agent for VMware fail to list VMs and other types of vSphere objects in the backup console in some cases.
[ABR-149418] Agent for Windows: When the VSS shadow storage limit is reached, a backup fails with the "The system cannot find the file specified" error instead of automatic restart.
[ABR-146975] Agent for VMware/Hyper-V: In some cases when backing up multiple VMs simultaneously (>5) by a single backup agent, the backup plan hangs on 97-100%.
[ABR-146865] Agent for Mac: The backup to SMB shares fails with the "Input/output" error after temporary network dropout even if the "Error handling" backup option is enabled (re-attempts do not work).
[ABR-140557] Agent for Hyper-V: Recovery of a EFI-based Hyper-V VM backup into a new VM may cause specific EFI boot entries to be missing in the VM configuration thus causing system unable to boot.
[ABR-140156] Agent for Linux: A backup of disks or volumes finishes with the "None of the items selected for backup were found" error on SLES 12 with enabled Secure Boot due to the Secure Boot restrictions to load 3rd party modules.
[ABR-136151] Agent for Windows: Memory leak in mms.exe ("Acronis Managed Machine Service" process) after a long running backup with the enabled VSS option.
[ABR-130522] Backup to Acronis Cyber Infrastructure storage (via Acronis Backup Gateway) fails after changing the IP/hostname address of Acronis Cyber Infrastructure and re-registration of it on the management server. Backup agents still try to use the old IP/hostname address.
[ABR-128222] Agent for VMware: A backup of VMware vCenter Virtual Appliance VM by Agent for VMware may complete with warnings due to temporary loss of connection to vCenter caused by its snapshot on the VMware level.
[ABR-126320] Service_process.exe may crash during a backup replication into an archive which contains a huge (>1000) amount of backups in it.
[ABR-138024] Browsing a network share by Agent for Linux may fail if the share contains some special symbols in its path (for example '#').
[ABR-69043] There is an unclear "Operation canceled by user" error message if a backup fails due to pre/post data capture commands failure.
