Snapshots are the first line of defense in any good data protection strategy.
- Perfect image of the virtual disk at a previous point in time
- Mountable as a read only volume for file recovery, operations or reporting
- Mountable as a live volume to turn back the clock
- Efficient snapshots - only changed, deduplicated blocks
- User selects size of snapshot area
- 3 methods: time scheduled, on-demand / manual, changed-data threshold
Server A
Server B
Server C
Tape provides off-site and long-term retention.
- Any tape drive or library can be attached
- Full image backup from any point-in-time snapshot
- Requires no backup software, licensing, or backup server
- Background copy - no operational disruption
- Data on tape retains original format & is independently restorable
- Directly-attached devices involve no network traffic (SAS ports)
- Can specify which slots to use on tape libraries
- Copy will span tapes if required
- Backup can be scheduled or performed on-demand
Quick, portable disk copies are invaluable for data accessibility.
- Copy any virtual disk to attached USB or eSATA disk
- Copy from any point-in-time using snapshot
- Data on disk retains same format as the original virtual disk
- Resulting disk is a mountable volume
- Background copy - no operational disruption
- Supports multiple disks, spanning, and encryption on disk
- Directly-attached devices involve no network traffic
- Copy can be initiated on-demand or scheduled
