These characters include colons (:), back slashes (\), question marks (?), ampersand (&), asterisk (*), and caret (^). Note:When you back up volumes with unsupported file systems, SmartSector copying is disabled (SmartSector backs up only those sectors on the volume that contain data). See “Viewing the details of the disk that you want to back up” on page 14. See “Scheduling a backup” on page 15. Scheduling a backup Veritas System Recovery 16 Linux Edition lets you schedule backups on a Linux computer. It provides a command line interface that lets you set the backup options and specify a schedule to run the backups. While scheduling backups, you can choose to create the following types of recovery points: ■ Independent recovery point Creates a complete, independent backup of the specified volumes or comma-separated multiple volumes. ■ Recovery point set Creates a base recovery point and additional recovery points that contain the incremental changes that aremade to the specified volumes or comma-separated multiple volumes To schedule a backup using Veritas System Recovery 16 Linux Edition 1 At the Linux server, log on as user root or a user with administrative privileges. 2 Enter the following command in a terminal window to start the schedule backup wizard: symsr -createjob Note: To exit the wizard, type q,Q, orQuit at any prompt other than the Select the source prompt or the Select destination prompt. 15Backing up a Linux computer Scheduling a backup 3 At the Select the source prompt, type the path of the volume block device or the mount point that you want to back up. You can provide multiple devices or mount points by using a comma (,) separator. 4 At the Select destination prompt, type the location where you want to create the recovery points. 5 At the Create machine specific folder prompt, type a y if you want to create a computer-specific folder in the backup destination. This option is useful if you use the same backup destination for multiple computers. When you back up a computer, its recovery points are stored in the folder specific to that computer. 6 At the Select recovery point type prompt, enter an appropriate option to specify the type of recovery point you want to create. See “Recovery point type options” on page 17. 7 At the Select compression level prompt, enter an appropriate option to set a compression level for the recovery points. See “Compression level options” on page 18. 8 At the Select encryption type prompt, enter an appropriate option to encrypt recovery point data or protect recovery point data using a password. See “Encryption type options” on page 18. 9 At the Backup schedule prompt, enter appropriate options to specify a schedule to run the backups. The backup schedule options vary depending on the recovery point type you have selected. See “Scheduling options for starting a new recovery point set (base recovery point)” on page 19. See “Scheduling options for creating recovery points (incremental recovery points)” on page 20. See “Scheduling options for an independent recovery point” on page 21. 10 At the Verify recovery point after creation prompt, type a y if you want to test whether the recovery point is valid or corrupt after it is created. 16Backing up a Linux computer Scheduling a backup 11 Review the backup job summary and then at the Save Job prompt, type a y to save the backup job. 12 At the Provide job name prompt, enter a name for the backup job. After you save a backup job, it is available in the system. You can view the details of the existing backups jobs if required. See “Viewing the details of existing backup jobs” on page 17. Viewing the details of existing backup jobs You can see a list of existing backup jobs and their details. To view the details of existing backup jobs 1 At the Linux server, log on as user root or a user with administrative privileges. 2 Enter the following command in a terminal window: symsr -info job See “Scheduling a backup” on page 15. Recovery point type options The following table describes the recovery point type options that you can select while scheduling a backup. See “Scheduling a backup” on page 15. Table 3-1 Recovery point type options DescriptionOption Creates a recovery point set of the specified volumes. This backup type requires less storage and is faster that independent recovery point because it contains only the incremental changes that were made to your computer since the previous recovery point Note: You can have only one recovery point set defined for each volume at any point of time. Recovery point set (recommended) Creates a complete, independent backup of the specified volumes. This backup type typically requires more storage space than the recovery point set, especially if you run the backup multiple times. Independent recovery point 17Backing up a Linux computer Scheduling a backup Table 3-4 Scheduling options for a new recovery point set (continued) DescriptionOption Starts a new recovery point set at the defined time and on the day of the month that you specify. Monthly Starts a new recovery point set at the defined time and on the first day of every quarter. Quarterly Starts a new recovery point set at the defined time and on the first day of every year. Yearly Scheduling options for creating recovery points (incremental recovery points) The following table describes the scheduling options for creating recovery points. See “Scheduling a backup” on page 15. Table 3-5 Scheduling options for creating recovery points DescriptionOption Lets you select the days and a start time for when you want to create the recovery points. Schedule Indicates that you want to create recovery points more than once a day to protect the data that you edit or change frequently. Run more than once per day Specifies the time that must occur between two recovery points. This option appears only if you have selected to create recovery points more than once in a day. Time between backups 20Backing up a Linux computer Scheduling a backup Table 3-5 Scheduling options for creating recovery points (continued) DescriptionOption Specifies the number of times the backup should run in a day. This option appears only if you have selected to create recovery points more than once in a day. Ensure that you specify a number considering the number of hours that you have specified to occur between two backups. For example, if you have specified a period of 10 hours to occur between backups, you cannot runmore than three backups a day. Number of times Scheduling options for an independent recovery point The following table describes the scheduling options for creating an independent recovery point. See “Scheduling a backup” on page 15. Table 3-6 Scheduling options for an independent recovery point DescriptionOption Creates the recovery point at the defined time and on the days of the week that you specify. Weekly Creates the recovery point at the defined time and on the day of the month that you specify. Monthly Creates the recovery point at the defined time and on the first day of every quarter Quarterly Creates the recovery point at the defined time and on the first day of every year. Yearly Creates the recovery point one time on the date and at the time that you specify. Run Only Once Running an existing backup job You can run an existing backup at any point of time. This option is useful in the following situations: 21Backing up a Linux computer Running an existing backup job ■ You modify a large number of files and you want to back them up immediately rather than waiting for the scheduled backup to run. ■ You want to back up your computer before you install a new application or before you make any changes to the operating system. To run an existing backup job 1 At the Linux server, log on as user root or a user with administrative privileges. 2 Enter the following command in a terminal window: symsr -runjob <job id> Replace <job id> with the ID of the backup job that you want to run. You can view the details of existing backup jobs to find out the ID of the backup job that you want to run. See “Viewing the details of existing backup jobs” on page 17. 22Backing up a Linux computer Running an existing backup job Recovering a Linux computer You can restore your computer (all volumes and partitions on your computer) using the recover feature of Veritas System Recovery 16 Linux Edition. If you have a recovery point for the partitions or volumes that you want to recover, you can fully recover your computer or another hard drive back to the state it was in when the recovery point was created. Restoring a system volume might require booting to and performing the recovery from the Veritas Recovery Disk. Note: If you restore a volume or partition that LVM (Linux Volume Manager) or software RAID managed, before you start the recovery process you must use lvmtools or the RAID tools that are present on the recovery disk to set up LVM or software RAID. 25Restoring a Linux computer Recovering a Linux computer To recover a computer 1 If the computer won't boot, start it using Veritas Recovery Disk. If the computer will boot, log on at a terminal window as user root or as a user with administrative privileges . See “Starting a Linux-based computer using Veritas Recovery Disk” on page 23. 2 If the recovery point is stored on a remote NFS or CIFS share, configure your network settings and mount the remote NFS or CIFS share. 3 Enter the following command at the server console: symsr -r recoverypoint_nameoptions -d destination Replace recovery point_name with the name of the recovery point you want to restore. Recovery points have a .v2i or .iv2i file name extension. Replace options with the options you want to use with the restore. Replace destinationwith the location where the recovery point is restored. The destination must be a partition or a volume device. For example, if you want to restore an independent recovery point named system_000.v2i (the system partition) from the /tmp/path/to directory back to its original location (/dev/sda1), you enter the following command: symsr -r /tmp/path/to/system_000.v2i -d /dev/sda1 -active Similarly, to restore an incremental recovery point named system_000_005.iv2i from a recovery point set, you enter the following command: symsr -r /tmp/path/to/system_000_005.iv2i -d /dev/sda1 -active Note: The -active option is only used with Veritas System Recovery 16 Linux Edition during a restoration of a system volume. Using the -active option allows the system to boot from a restored volume. Also, in order for a system to boot correctly from a restored system volume, you might be required to fix the Grub boot loader using the grub-install tool. You might also need to update the /etc/fstab. See “About restoring to empty disk segments” on page 27. See “Mounting and unmounting a recovery point for granular file and folder recovery” on page 27. 26Restoring a Linux computer Recovering a Linux computer About restoring to empty disk segments Veritas System Recovery 16 Linux Edition lets you restore to an MBR (Master Boot Record) partition, GPT and LVM devices, Software RAID, or to free space on the disk. If you restore to free disk space (an empty disk segment), an MBR partition (on an MBR disk) or a GPT entry (on a GPT disk) is created regardless of the partition type that the recovery point was created from For example, suppose you have a 40 GB hard disk (/dev/sda) that is partitioned as follows: /dev/sda1=20GB Free Space=20GB To restore a recovery point named backup01.v2i to free space, you use the following command: symsr -r backup01.v2i -d /dev/sda -seg 1 Note: To find the empty segment number, you can use the following command: symsr -info disk After the recovery is complete, the disk has the following partitions with the restored volume on the /dev/sda2 partition: /dev/sda1 /dev/sda2 See “Mounting and unmounting a recovery point for granular file and folder recovery” on page 27. Mounting and unmounting a recovery point for granular file and folder recovery Veritas System Recovery 16 Linux Edition creates partition or volume-level recovery points. If you want to restore individual files, folders, and documents, you must first mount the recovery point that includes those files and folders. The Granular File Recovery utility is included with Veritas System Recovery 16 Linux Edition and can be used to mount recovery points. After mounting a recovery point using the Granular File Recovery utility, you can restore individual files, folders, and documents. While mounting a recovery point, you may experience the following error: 27Restoring a Linux computer Mounting and unmounting a recovery point for granular file and folder recovery To unmount a recovery point 1 Open a terminal window (command-line terminal) on the Linux server and log on as a user with mount privileges. 2 Enter the following command in a Linux terminal window: umount /mnt/image Replace /mnt/image with the path to where the recovery point is mounted.

For example, if you have specified a period of 10 hours to occur between backups, you cannot run more than three backups a day. Specify independent recovery point schedule Lets you schedule backups to create independent recovery points. The following scheduling options are available: [1]Weekly Runs the backup on the day of the week you specify. By default, the backup runs on Sunday [SUNDAY]. [2] Monthly Runs the backup on the days of the month you specify. You can choose to run the backup every day, on a specific day, or on the last of day of the month. By default, the backup runs on the first day of the month [1]. [3] Quarterly Runs the backup on the first day of every quarter. If you choose this option, the backup runs on the first day of January, April, July, and October. [4] Yearly Runs the backup on the first day of January. [5] Run only once Runs the backup only once. Note: The default schedule for running backups is Weekly [1]. Recur every week Runs the backup on the days of the week you specify. You can choose to run the backup on one or more days of the week. By default, the backup runs on Sunday [SUNDAY]. Specify backup start time Runs the backup at the time on the days that you specified. 47Veritas System Recovery for Linux Utilities Backup and Restore (symsr utility) symsr -r system_000.v2i -d /dev/sda -segment 0 Restores the system partition back to its original location (/dev/sda1) on a new or empty disk. symsr -r lvm2_000.v2i -d /dev/mapper/vg0-lv1 Restores an LVM device back to its original location (/dev/mapper/vg0-lvl). symsr -rmjob job-1 Removes the backup job corresponding to the specified job ID. symsr -runjob job-4 Runs the backup job corresponding to the specified job ID immediately, irrespective of the backup schedule. symsr -v Shows the information about the product name, version, and the license status. symsr -vrp system_000.v2i Verifies the integrity of the recovery point. symsr -vrp system_000_s01.v2i Verifies the integrity of the spanned recovery point and the recovery point chain.

SYNOPSIS mount -t v2i [recovery point]... [mount point]... [options]... DESCRIPTION mount.v2i mounts a recovery point. It is usually invoked indirectly by the mount(8) command when using the -t v2i option. This command requires the FUSE driver and the FUSE shared library (libfuse.so.2). mount -t v2i is a command line utility for mounting a recovery point file on a Linux computer so you can restore files and folders. Using the mount -t v2i command line utility involves specifying the image file name, the location where the recovery point will be mounted, and any desired options. You must use the -o flag when specifying options. Use umount command to unmount the.v2i file that is mounted using the mount -t v2i command. OPTION password=<password> If the recovery point is assigned a password, use this option to supply the password when mounting or unmounting the file. If a password is not supplied for the password-protected recovery point, it prompts you for the password. EXAMPLES The following are usage examples for mounting a recovery point using mount -t v2i and unmounting a recovery point using unmount. mount -t v2i image.v2i /mnt/image Mount a recovery point in the /mnt/image directory. Replace image.v2i with the name of the recovery point. 51Veritas System Recovery for Linux Utilities Granular File Recovery (mount.v2i utility) mount -t v2i image_nnn.iv2i /mnt/image Mount an incremental recovery point in the /mnt/image directory. Replace image_nnn.iv2i with the name of the incremental recovery point. For example, if you want to mount the fifth incremental recovery point, replace image_nnn.iv2i with image_005.iv2i. mount -t v2i image.v2i /mnt/image -o password=password Mount a password-protected recovery point in the /mnt/image directory. Replace image.v2iwith the name of the recovery point and passwordwith the password. umount /mnt/image Unmount a recovery point in the /mnt/image directory.
