Client settings properties for UNIX clients

To access this setting, in the web UI select Hosts > Host properties. Select the UNIX client. If necessary click Connect, then click Edit client. Click UNIX client > Client settings.

The UNIX Client settings properties apply to currently selected NetBackup client running on the UNIX platform.

The UNIX Client settings host properties contain the following settings.

Table: UNIX Client settings properties

Property	Description
Locked file action	Determines what happens when NetBackup tries to back up a file with mandatory file locking enabled in its file mode. Select one of the following options: Wait By default, NetBackup waits for files to become unlocked. If the wait exceeds the Client read timeout host property that is configured on the primary server, the backup fails with a status 41. See Timeouts properties. Skip NetBackup skips the files that currently have mandatory locking set by another process. A message is logged if it was necessary to skip a file.
File compression memory	Specifies the amount of memory available on the client when files are compressed during backup. If you select compression, the client software uses this value to determine how much space to request for the compression tables. The more memory that is available to compress code, the greater the compression and the greater the percentage of computer resources that are used. If other processes also need memory, use a maximum value of half the actual physical memory on a computer to avoid excessive swapping. The default is 0. This default is reasonable; change it only if problems are encountered.
Reset file access time to the value before backup	Specifies that the access time (atime) for a file displays the backup time. By default, NetBackup preserves the access time by resetting it to the value it had before the backup. Note: This setting affects the software and the administration scripts that examine a file's access time. Note: If NetBackup Accelerator is used to perform the backup, this setting is ignored. Accelerator does not record and reset the atime for the files that it backs up. See Accelerator notes and requirements.
Keep status of user-directed backups, archives, and restores	Specifies the number of days to keep progress reports before the reports are deleted. The default is 3 days. The minimum is 0. The maximum is 9,999 days. Logs for user-directed operations are stored on the client system in the following directory: install_path\NetBackup\logs\user_ops\loginID\logs
Use VxFS File Change Log (FCL) for incremental backups	Determines if NetBackup uses the File Change Log on VxFS clients. The default is off.
Default cache device path for snapshots	This setting identifies a raw partition available to the copy-on-write process. This raw partition is used when either nbu_snap or VxFS_Snapshot are selected as the snapshot method. The partition must exist on all the clients that are included in the policy.
Add	Adds the file endings to the list of file endings that you do not want to compress. Click Add, then type the file extension. Click Add to add the ending to the list.
Do not compress files ending with these file extensions	Specifies a list of file extensions. During a backup, NetBackup does not compress files with these extensions because the file may already be in a compressed format. Do not use wildcards to specify these extensions. For example, .A1 is allowed, but not .A* or .A[1-9] Files that are already compressed become slightly larger if compressed again. If compressed files with a unique file extension already exist on a UNIX client, exclude it from compression by adding it to this list. Corresponds to adding a COMPRESS_SUFFIX =.suffix option to the bp.conf file.
