restore – The Opposite of the Dump Command

The restore command in Linux is used to restore files and directories from backups created with the dump command. It is the opposite of the dump command, which creates a backup of files and directories.

Overview

The restore command is used to restore files and directories from backups created with the dump command. The restore command reads the backup file and restores the files and directories to their original location. The user must have root privileges to run the restore command.

The basic syntax for the restore command is as follows:

restore -f backup-file

The -f option specifies the backup file to be restored. If the backup file is not specified, restore will prompt the user to enter the backup file name.

The restore command can be used to restore specific files or directories by specifying their path. For example, to restore a file named file.txt from a backup, use the following command:

restore -f backup-file /path/to/file.txt

To restore a directory and all its contents, use the following command:

restore -f backup-file /path/to/directory/

Options

The following table lists the available options for the restore command:

Option Description
-f file Specifies the backup file to be restored.
-i Interactive mode. Prompts the user before restoring each file.
-r Restore directories recursively.
-t Test mode. Displays the contents of the backup file without restoring them.
-v Verbose mode. Displays detailed information about the restore process.

Troubleshooting Tips

  • If you receive an error message that says “Permission denied”, make sure you are running the restore command with root privileges.
  • If you are having trouble restoring a specific file or directory, make sure it is included in the backup file.
  • If you accidentally overwrite a file during the restore process, you can use the undelete command to recover the original file.

Notes

  • The restore command can only restore files and directories that were backed up with the dump command.
  • The restore command does not create backups. To create backups, use the dump command.
  • The restore command can be used to restore files and directories from remote backups by specifying the remote backup file location.
