====== AhsayACB ===== Last modified: 2023/06/20 AhsayACB is the agent for backing up files on desktops and laptops, cloud files, as well as Microsoft 365 as individual user. {{public:ahsay_wiki_software_acb_requirement_01.png?600}} ===== System Architecture ===== Below is the system architecture diagram illustrating the major elements involved in the backup process among the backup machine, AhsayACB and AhsayCBS. {{public:ahsay_wiki_software_acb_requirement_02.png?650}} ---- ===== Requirements ===== ==== General ==== === Hardware Requirements === For details of the minimum and recommended requirements for installing AhsayACB, refer to: [[public:version_9:start_here:9000_ahsay_hardware_requirement_list_hrl_for_version_9.1_or_above|Ahsay Hardware Requirement List (HRL)]] === Software Requirements === For the list of compatible operating systems, refer to: [[public:version_9:start_here:9005_ahsay_software_compatibility_list_scl_for_version_9.1_or_above|Ahsay Software Compatibility List (SCL)]] For the list of compatible operating system for OpenDirect, refer to: [[public:version_9:start_here:9006_ahsay_scl_for_granular_and_opendirect_restore_v9 |Ahsay Software Compatibility List (SCL) for Granular and OpenDirect Restore]] === Antivirus Exclusion Requirement === To optimize performance of AhsayACB on Windows, and to avoid conflict with your antivirus software, refer to this [[public:version_9:start_here:9023_suggestion_on_antivirus_exclusions|list of processes and directory paths that should be added to all antivirus software white-list / exclusion list]]. ==== Windows ==== The bJW.exe process is automatically added to Windows Defender exclusion list for Windows 10, during installation / upgrade via installer or upgrade via AUA. ==== Mac OS X ==== These are the limitations to AhsayOBM running on Mac OS X: === Installation on Root Drive === AhsayACB must be installed on the root drive of a volume (e.g. /Applications/...). === Resource Fork Files === Resource fork files cannot be restored with AhsayACB installation on Mac OS X 10.8 above. === Case-Insensitive File System === For volume with a case-insensitive file system, target file of a symbolic link will be backed up twice (in both upper case and in lower case), hence, doubling the backup quota storage requirement. ---- ===== Documentation ===== * [[https://www.ahsay.com/jsp/en/downloads/ahsay-downloads_documentation_guides-acb.jsp|AhsayOBM and AhsayACB guides]]
