The options that follow determine the backup method used for the backup.
- File Mode--Lets you protect individual files and directories. File mode backup lets you perform the tasks that follow:
- Back up files and directories at file level granularity contained in VM.
- Perform full, incremental, and differential backups.
- Restore data at file level granularity.
- Process multiple streams of data simultaneously using the Multistreaming option.
- Filter data using the Filter option.
Note: The elapsed time required to perform a file level backup of a full VM is greater than the elapsed time required to perform a raw (full VM) level backup of the same volume.
- Raw Mode--Lets you protect entire systems for disaster recovery. Raw mode backup lets you perform the tasks that follow:
- Perform full backups of full VM images only.
- Process multiple streams of data simultaneously using the multistreaming option.
Note: Raw mode does not let you restore data at file level granularity or filter raw (full VM) data. Filters applied to raw mode (full VM) backups are ignored at runtime.
- Mixed Mode--Mixed mode is the default backup mode. Mixed mode lets you perform the tasks that follow:
- Perform GFS and rotation backup jobs that consist of weekly full backups in full VM (raw) mode and daily incremental and differential backups in file mode in a single backup job.
Note: Rotation and GFS rotation jobs are advantageous in that they contain backup data that provides you with daily protection (file level backups) and disaster recovery protection (raw, full VM backups) in a single backup job.
- Allow file level restore--Lets you back up data using Raw Mode efficiency and restore data with File level granularity. To perform granular file level restores from raw (full VM) backups, you must specify the name of the CA ARCserve Backup server on your VMs. For more information, see Specify the Name of the CA ARCserve Backup Server.
Allow file level restore lets you perform the tasks that follow:
- Restore data at file level granularity from Raw Mode (full VM) backups.
- Restore data at file level granularity from Mixed Mode backups.
With the Allow file level restore option, CA ARCserve Backup demonstrates the following behavior:
- You can use the Allow file level restore option with all types of backups, including custom backups, rotation backups, and GFS rotations that consist of full, incremental, and differential backups. The full backups are captured in raw (full VM) mode and the incremental and differential backups are captured in file level backup mode. If you do not specify Allow file level restore, CA ARCserve Backup restores only the incremental and differential backups. The full backup, which is captured in Raw mode, is not packaged with the restore.
- CA ARCserve Backup cannot restore data at file level granularity when performing raw mode backups and mixed mode backups of data that resides on dynamic disks connected to Windows 2000 Server systems.
