When restoring data, you can specify the following options:
Locked File Options
When restoring data from a Windows, Linux or UNIX local job, you can can specify whether to overwrite locked files with restored files with the same names. You can select one of the following options:
•Yes, overwrite locked files – Files on the system that are locked during the restore are overwritten by restored files when the system restarts. You must select this option for a system state or system volume restore.
•No, do not overwrite locked files – Files on the system that are locked during the restore are not overwritten by restored files with the same name.
Streams
When running a backup, information is collected from your files in various streams. Original data created by a user is called a data stream. Other information, such as security settings, data for other operating systems, file reference information and attributes, are stored in separate streams.
When restoring data from a Windows, Linux or UNIX local job, you can select one of the following options:
•Restore all streams – Restores all information streams. This option is recommended if you are restoring files to a system with an identical platform.
•Restore data streams only – For cross-platform restores, restores data streams only. This option ensures that conflicts do not arise as a result of system-specific information streams.
Log Options
Select one of the following job logging levels from the list:
•Files — Provides the most detailed information, and is typically used for troubleshooting. Provides information about files that are backed up.
•Directory — Provides less detail than the Files logging level. Provides information about folders that are backed up.
•Summary — Provides high-level information, including the vault and Agent version, and backup sizes.
•Minimal — Provides high-level information, including the vault and Agent version.
Changing the logging level only affects log files that are created from that point and after. It does not affect previously-created log files.
Note: For Image Plug-in jobs, the selected logging level does not affect the content of the logs.
Performance Options
To use all available bandwidth for the restore, select Use all available bandwidth.
Bandwidth throttling settings specify the amount of bandwidth consumed by an Agent for backups and, in the case of most Agents, restores. For example, you might want to restrict the amount of bandwidth used for daytime backups so that online users are not affected, and allow unlimited bandwidth usage at night so that scheduled backups run as fast as possible.
Bandwidth throttling values are set at the computer (Agent) level for most Agents, and apply to both backups and restores. If three jobs are running at the same time on the same computer, each job gets 1/3 of the specified maximum bandwidth. For the Hyper-V Agent, bandwidth throttling is applied at the Host level, and applies only to backups. If three VMs are being backed up on a node, each gets 1/3 of the specified maximum bandwidth on the node. The total bandwidth sent to the vault can be as high as the specified maximum multiplied by the number of nodes where the Host service is installed.
Bandwidth settings include:
•Maximum bandwidth (upper limit), in megabits per second, to be consumed by the Agent for all backups and restores
•Period of time during the day that throttling is in effect. Only one time window can be specified. Outside the window, no throttling takes place.
•Days of the week that throttling is in effect
If the bandwidth throttling time period begins when a backup is underway, the maximum bandwidth is applied dynamically to the running backup. Similarly, if the bandwidth throttling time period ends when a backup is running, bandwidth throttling is ended for the backup.
If you edit an Agent’s bandwidth settings while a backup is running, the new Agent settings do not affect the backup that is running. Bandwidth settings are applied when a backup starts, and are not applied to backups that are already running.
