Traffic jaringan
Traffic antara appliance pencadangan/pemulihan dan agen Pencadangan dan DR di
host Anda dienkripsi dan berkomunikasi melalui SSL. Agen Pencadangan dan DR menggunakan
port 5106 secara default untuk komunikasi dari appliance. Pastikan
firewall Anda mengizinkan komunikasi melalui port ini. Jika Anda sudah memiliki layanan
yang menggunakan port ini, hubungi Dukungan untuk mendapatkan bantuan.
Software antivirus
Berikut adalah beberapa rekomendasi tingkat tinggi untuk software antivirus. Produk anti-virus atau keamanan
tertentu mungkin menyebut sesuatu dengan nama yang berbeda, tidak mendukung
beberapa fitur karena pengecualian proses biasanya tidak didukung, dan dikonfigurasi
dengan cara yang berbeda.
Kecualikan proses udsagent dari Pemantauan Antivirus: Hal ini
biasanya disebut pengecualian proses atau tingkat ancaman proses. Mengecualikan
apa pun yang dilakukan UDSAgent.exe untuk Windows atau udsagent untuk Linux dari
pemindaian akan memberikan performa terbaik untuk pencadangan dan peluang paling kecil
software antivirus memblokir apa pun.
Kecualikan pemindaian disk staging yang terpasang: Cegah software
antivirus memindai file yang ditulis oleh Layanan Pencadangan dan DR ke
disk staging. Proses ini biasanya lebih lambat daripada membaca file di
volume yang sudah dilindungi.
Windows
C:\Windows\act\*.*
C:\Windows\act\
C:\Program Files\Google Cloud Backup and DR\UDSAgent.exe
C:\Program Files\Google Cloud Backup and DR\driver\aamservice.exe
C:\Program Files\Google Cloud Backup and DR\log\*.*
C:\Program Files\Google Cloud Backup and DR\tmpdata\*.*
C:\Program Files\Google Cloud Backup and DR\act_scripts
Linux
/opt/act/bin/udsagent
/act/mnt
Nonaktifkan heuristik antivirus: Tindakan ini tidak diperlukan, tetapi dapat membantu dalam
beberapa kasus. Heuristik antivirus biasanya memblokir operasi yang terlihat
mencurigakan. Saat menjalankan pencadangan volume
sistem, agen Pencadangan dan DR terlihat mencurigakan karena membaca konten
direktori Windows dan membuatnya ulang di disk staging.
Dalam beberapa kasus, menonaktifkan software antivirus gagal mencegah kegagalan
pencadangan, tetapi menonaktifkan heuristik software antivirus memungkinkan image
pencadangan berhasil.

Also, Backup and DR agents enable backups of Microsoft SQL Server\n clusters running on VMware VMs.\n\n- When the Backup and DR agent manages data movement, the backup/recovery appliance\n presents a staging disk to store a copy of changed application\n data during each snapshot job.\n\nObtain the right Backup and DR agent for your host\n--------------------------------------------------\n\nThe management console has four different Backup and DR agent installer files.\nEach is of a file type appropriate to its intended host type.\n\nDownload a Backup and DR agent installer file\n---------------------------------------------\n\nYou can download a Backup and DR agent installer file with a web browser from\nthe management console using the following steps:\n\n1. In the management console, go to the **Manage** drop-down menu and click\n **Appliances**.\n\n2. Right-click an appliance and select **Configure Appliance**.\n\n3. Select **Agent Management**. The four installer files appear at the top\n of the window. Download the agent installer file that you need.\n\n4. Depending on your host operating system, install the Backup and DR agent:\n\n - To install the Backup and DR agent on the Linux host, refer to\n [Install the Backup and DR agent on a Linux host](/backup-disaster-recovery/docs/configuration/linux-agent).\n\n - To install the Backup and DR agent on the Windows host, refer to\n [Install the Backup and DR agent on a Windows host](/backup-disaster-recovery/docs/configuration/windows-agent).\n\n | **Note:** Port 5106 must be open for `UDSAgent` to ensure that the backup/recovery appliance can communicate with the Backup and DR agent on the host. This requires an ingress firewall rule where the backup/recovery appliance is the source, the host running the agent is the target, and the target port is 5106. Also, you don't need to add port 5106 to the default ingress rule created for the appliance, as this specifies the appliance as the target.\n5. When the installation is complete, a secret key displays. Save the\n secret key in a notepad or in a text editor, you need to add this in the\n Backup and DR agent section in [Linux](/backup-disaster-recovery/docs/configuration/add-linux-hosts)\n or [Windows](/backup-disaster-recovery/docs/configuration/supported-windows)\n hosts. This secret key is valid for two hours.\n\nNetwork traffic\n---------------\n\nTraffic between the backup/recovery appliances and the Backup and DR agent on\nyour hosts is encrypted and communicates by SSL. The Backup and DR agent uses\nport 5106 by default for communication from the appliance. Make sure your\nfirewall permits communication through this port. If you have existing services\nusing this port, contact Support for assistance.\n\nAntivirus software\n------------------\n\nThese are some high-level recommendations for antivirus software. Specific\nantivirus or security products may call things by different names, not support\nsome features as process exclusion is commonly not supported, and are configured\nby different means.\n\n- **Exclude the `udsagent` process from Antivirus Monitoring** : This is\n typically called process exclusion or process threat level. Excluding\n anything that `UDSAgent.exe` for Windows or `udsagent` for Linux does from\n scanning provides the best performance for the backup and the least chance\n that the antivirus software blocks anything.\n\n- **Exclude scanning of mounted staging disks**: Prevent the antivirus\n software from scanning the files that Backup and DR Service writes to the\n staging disk. This is typically slower than reading files on the\n protected volume already.\n\n ### Windows\n\n C:\\Windows\\act\\*.*\n C:\\Windows\\act\\\n C:\\Program Files\\Google Cloud Backup and DR\\UDSAgent.exe\n C:\\Program Files\\Google Cloud Backup and DR\\driver\\aamservice.exe\n C:\\Program Files\\Google Cloud Backup and DR\\log\\*.*\n C:\\Program Files\\Google Cloud Backup and DR\\tmpdata\\*.*\n C:\\Program Files\\Google Cloud Backup and DR\\act_scripts\n\n ### Linux\n\n /opt/act/bin/udsagent\n /act/mnt\n\n | **Note:** You might still have failures if the antivirus software blocks the Backup and DR agent from opening or reading a file on the protected volume.\n- **Disable antivirus heuristics**: This is not required, but may help in\n some cases. Antivirus heuristics typically block operations that look\n suspicious. When the Backup and DR agent is running a backup of a system\n volume, it looks suspicious since it is reading the contents of the\n Windows directory and recreating it on the staging disk.\n\n In some cases, disabling the antivirus software fails to prevent backup\n failures, but disabling the antivirus software heuristics allows backup\n images to succeed.\n\nWhat's next\n-----------\n\n- To install Backup and DR agent on a Linux host, see [Install the Backup and DR agent on a Linux host](/backup-disaster-recovery/docs/configuration/linux-agent)\n\n- To install Backup and DR agent on a Windows host, see [Backup and DR agent on Windows hosts](/backup-disaster-recovery/docs/configuration/windows-agent)\n\n- To upgrade Backup and DR agent, see [Maintain Backup and DR agents on hosts](/backup-disaster-recovery/docs/configuration/manage-agent)"]]
