Windows 示例：\\SERVERNAME\SHARENAME\abc 会备份文件共享中的 abc 目录。
修剪路径：在修剪路径字段中提供修剪路径。修剪路径用于指定文件系统中目录遍历停止的点。
Linux 示例：/usr/local/lib 可确保不复制 /usr/local/lib 后面的任何内容，但会复制 /usr/local 中的所有其他目录和文件。
Windows 示例：\\SERVERNAME\SHARENAME\abc 可确保不会复制 \\SERVERNAME\SHARENAME\abc 后面的任何内容，但会复制 \\SERVERNAME\SHARENAME 中的所有其他目录和文件。
如果此字段留空，目录遍历将深入到要备份的起始路径的每个子目录。
服务接入点 IP 地址：如果文件系统是集群资源，并且您希望无论哪个集群节点托管文件系统，都对其进行备份，请将集群资源 IP 地址指定为服务接入点 IP 地址。这样，备份/恢复设备便可以使用集群资源 IP 连接到备份和灾难恢复代理，并从活跃的集群节点备份文件系统。为了确保备份在所有集群节点上正常运行，必须在所有集群节点上安装 Backup and DR 代理。输入集群应用的虚拟 IP 地址。对于故障切换集群，此参数用于查找备份的活跃节点。对于主动/主动集群，这是可用于备份的符合条件的服务器的逗号分隔列表。
使用 Service IP 进行恢复：在恢复集群应用期间，遵循 Service Access Point IP 地址。如果您想使用服务 IP 地址恢复集群应用，请选择 Yes。如果您不想使用服务 IP 地址进行恢复，请选择否。
备份和灾难恢复代理选项：除非您正在与支持团队合作，否则请将备份和灾难恢复代理选项留空。
为单个暂存磁盘优先使用 LVM：即使单个暂存磁盘足以进行备份，也要创建 LVM。如果您想使用基于 LVM 的暂存磁盘，并且无论 Linux 源磁盘的大小如何，都可以在不进行新的完整备份的情况下进行扩展，请选择 Yes。如果您不想使用基于 LVM 的已展开暂存磁盘，请选择否。

Valid entries are one\n to 256000. By default, the Backup and DR agent uses the size of the managed file\n system as the size of the staging disk. This setting allows the administrator\n to override this value to allow for growth of the file system.\n\n- **Use Staging Disk Granularity as Minimum Staging Disk Size** : The default\n value is zero when you select **No** . If you select **Yes** , then you must\n enter a value in GB in the **Staging disk granularity** field.\n This setting is for applications that are less than the size of the\n granularity setting and tend to grow periodically. This setting helps\n avoid frequent and costly full backups. There is no initial cost to using\n a staging disk that is larger than required for immediate use because the\n staging disk is thin-provisioned.\n\n- **Staging Disk Granularity (GB)**: Defines the granularity of the staging\n disk created for an out-of-band application. It specifies the size of each\n staging disk when multiple staging disks are used for an application.\n Valid entries are one to 128000. For example, the following:\n\n - If an application is 4.3TB, and the **Stage Disk Granularity** value is 2TB and **Last Staging Disk Minimum Size** value is 1TB, the backup/recovery appliance creates three staging disks of 2T, 2T, and 1T.\n - If an application is 4.3TB, and the **Stage Disk Granularity** value is 2TB and **Last Staging Disk Minimum Size** value is 0.1TB, the backup/recovery appliance three staging disks of 2T, 2T, and 0.3T.\n - If an application is 4.3TB, and the **Stage Disk Granularity** value is 5TB and **Last Staging Disk Minimum Size** value is 1TB, the backup/recovery appliance creates one staging disk of 4.3T. **Stage Disk Granularity** and **Last Staging Disk Minimum Size** are specified at the application level and override the system-wide default values.\n- **Staging Disk Mount Point** : Enter a **Staging Disk Mount Point** if you\n need the staging disk mounted to a particular location.\n\n- **Exclude Patterns, Include Patterns** : Enter the filename pattern to be\n excluded from or included in backup. The backup/recovery appliance offers the\n ability to exclude or include certain file types. Using either the\n **Exclude Patterns** or **Include Patterns** option, only the most crucial data\n is backed-up leaving a side the non-critical files. The guidelines include the\n following:\n\n - Only files are excluded or included, this does not impact directories.\n - A pattern can include wildcard characters, for example, an asterisk (\\*) or a question mark (?). To exclude all the files that contains `.sys` as extension, enter `*.sys` in the **Exclude Pattern** or **Include Pattern** field.\n - On Windows, files named `pagefile.sys` and `hiberfil.sys` that appear in the root directory of a drive are automatically ignored.\n- **Start Paths** : Specifies the point in the file share where backup starts.\n If the **Start Path** field is left blank, backup starts at the root directory\n of the file system to be backed-up.\n\n Linux example: `/usr/local` backs up the `/usr/local` directory.\n\n Windows example: `\\\\SERVERNAME\\SHARENAME\\abc` backs up the abc directory\n on the file share.\n- **Prune Paths** : Provide the prune paths in the **Prune Paths** field. Prune\n path specifies a point in the file system where directory traversals stop.\n\n Linux example: `/usr/local/lib` ensures that nothing following\n `/usr/local/lib` is copied, but all other directories and files in\n `/usr/local` are copied.\n\n Windows example: `\\\\SERVERNAME\\SHARENAME\\abc` ensures that nothing\n following `\\\\SERVERNAME\\SHARENAME\\abc` is copied, but all other directories and\n files in `\\\\SERVERNAME\\SHARENAME` are copied.\n\n If this field is left blank, the directory traversal descends into every\n subdirectory of the start paths being backed up.\n- **Service Access Point IP Address**: If a file system is a cluster resource\n and if you want it to be backed up irrespective of which cluster node is\n hosting the file system, then specify the cluster resource IP as a service\n access point IP. This allows the backup/recovery appliance to connect to the\n Backup and DR agent using the cluster resource IP and to back up the\n file system from the active cluster node. For backup to work correctly\n across all cluster nodes, the Backup and DR agent must be installed on all\n cluster nodes.\n Enter a virtual IP address for a clustered application. For failover clusters,\n this is used to find the active node for a backup. For active/active clusters,\n this is a comma separated list of eligible servers that can be used for the\n backup.\n\n- **Use Service IP for Restore** : Honor the service access point IP address\n during restore for a clustered application. Select **Yes** if you want to use\n the service IP address for restoring a cluster application. Select **No** if\n you do not want to use the service IP address to restore.\n\n- **Backup and DR Agent Options**: Leave Backup and DR agent options blank\n unless you are working with support.\n\n- **Prefer LVM for Single Staging Disk** : Create an LVM even when a single\n staging disk is enough for backup. Select **Yes** if you want to use an LVM-based\n staging disk that can be expanded without requiring a new full backup,\n regardless of the size of the Linux source disk. Select **No** if you do not\n want to use an expanded LVM-based staging disk.\n\nBackup and DR Service for Filestore and file systems\n----------------------------------------------------\n\nThis page is one in a series of pages specific to protecting and recovering\nfilesystems with Backup and DR Service.\nYou can find additional information in the following pages:\n\n- [Backup and DR for file systems](/backup-disaster-recovery/docs/concepts/backupdr-for-filesystems)\n- [Manage hosts and their connected applications](/backup-disaster-recovery/docs/configuration/manage-hosts-and-their-connected-applications)\n- [Configure application details and settings to protect file system data](/backup-disaster-recovery/docs/backup/configure-app-settings-for-filesystems)\n- [Apply a backup plan to protect a file system](/backup-disaster-recovery/docs/create-plan/apply-backup-plan-to-filesystem)\n- [Restore a file system to the source](/backup-disaster-recovery/docs/access-data/filesystem-restore)\n- [Mount a file system or file share](/backup-disaster-recovery/docs/access-data/mount-file-system)\n- [Mount and migrate a file system for instant recovery to any target](/backup-disaster-recovery/docs/access-data/filesystem-mount-and-migrate)"]]
