Disk-to-disk backup is a process of backing up data from one hard disk to another hard disk, instead of using tape or cloud backup. This method offers faster backup and restore times, higher speeds and capacity than tape backup, and reduced backup windows.
Differences with Virtual Tape and Remote Backup Services
Disk-to-disk backup differs from Virtual Tape as it enables multiple backup and restore functions simultaneously using a real file system. On the other hand, remote backup services only differ in that the backed-up data is kept at a remote location, and the service is usually provided by a managed backup provider.
The Benefits of D2D Backup
The benefits of disk-to-disk backup are faster transfer speeds than using tape or disk, shorter backup and restore times, nonlinear data recovery for shorter and easier file recovery, and lower total cost of ownership due to lower hardware prices and advances in automation.
Backup to Solid-State Drives (SSDs)
Backup to solid-state drives (SSDs) has become a viable alternative to traditional hard disk drives (HDDs) for backing up heavily used databases, due to the higher speed and performance of flash storage. However, the cost of flash storage is still higher than that of HDD backups. But since the capacity of SSDs is now greater than that of HDDs, they could play a larger role in data backup.
Frequently Asked Questions
Why is disk-to-disk backup faster than tape backup?
Disk-to-disk backup is faster than tape backup because it eliminates the need for multiple read/write operations, allows for better performance optimization, and eliminates the need for loading, unloading, rewinding and fast-forwarding tapes.
What are the benefits of using solid-state drives (SSDs) for backup?
SSDs offer faster backup and restore times, higher speed and performance, and greater capacity than traditional hard disk drives (HDDs). This makes them a good option for those looking to backup heavily used databases.
How can disk-to-disk backup reduce backup windows?
Disk-to-disk backup works by backing up data from one hard disk to another hard disk. This eliminates the need for multiple read/write operations, allows for better performance optimization, and reduces overall backup time.
In conclusion, disk-to-disk backup is a great option for those looking for faster backup and restore times, higher speeds and capacity than tape backup, and a reduced backup window. Additionally, backup to solid-state drives can offer faster performance for heavily used databases. Switching to disk-to-disk backup could help streamline your backup process and save you time and money.
