Besides disk and tape, backing up data to network location is also a good choice since the stored data can be access without inserting portable devices, and unaffected by disk failures.ĪOMEI Centralized Backupper can back up your crucial data to network share or NAS centrally and manage the backup tasks from a central console. Network backup can be a fine addition to tape & disk backupĪccording to the 3-2-1 backup rule, it is better to store data in different locations. The disk may fail to start, which leads to data loss.Īfter learning the tape vs disk backup pros and cons, you may be able to make your own choice, or combine them to build a backup strategy. ![]() Hardware unavailability after updating.ĥ. Because the disk is always on, the lifecycle is relatively short and requires additional costs on electricity, cooling, maintenance.Ĥ. Space cost intensive, relatively large storage capacity per TB.ģ. Some disk-based cartridge solutions offer the benefits of disk backup as well as the portability and media rotation of tape backup such as Iomega’s REV drive and Tandberg’s rdx Quikstor drive.Ģ. Using additional technology (RAID, NAS) can be conglomerated to large capacities and achieve high throughput.ĥ. You can look up specific files from the disk system for quick disaster recovery.Ĥ. Disk backup eliminates the time it takes to mount a tape, search for the correct position and locate the data you want to restore. However, disk backup offers you random access to data storage.ģ. Tape backup is to store data sequentially. The initial cost of a tape drive and tape media setup is often more expensive than an equivalent disk-based backup.Ģ. These drawbacks can be effectively fixed by using effective backup software which helps you to perform data backup better.ġ. If you store data on offsite disks, performing data recovery will take more time. Requires special drives or tape libraries.Ĥ. Not suitable for regular backups, reuse of tapes can be easily damaged.ģ. Require a special drive or tape library.Ģ. Scaling a tape backup system is simple, which only requires to add more tape cartridges.ġ. For some information (e-mail, documents, financial records, patient medical records, etc) that needs to be retained permanently, tape is more secure than disk and is easier to transport offsite.Ĥ. Long-term archiving and off-site storage. Less sensitive to mechanical damage thanks to no permanently spinning parts.ģ. ![]() Tape backup costs lower price per TB and it doesn’t require additional costs on maintenance, electricity, cooling.Ģ. ![]() You can refer to these advantages and disadvantages to better meet your business data storage requirements and protect your information.ġ. The copied data is written to tape sequentially, one file after another, and access is also sequential.ĭisk backup (disk-based backup) refers to backing up data to hard disk storage unit for disaster recovery (DR) in a large enterprise.Īfter understanding the basic concepts of tape backup and disk backup, we will go through the pros and cons of tape and disk backup solutions to help you choose the suitable data storage. LTO (Linear Tape-Open) is a standard for magnetic data tape. Tape backup is moving data from hard drive to tape cartridge for long-term archiving or data recovery in the event of computer corruption. Tape and disk are the main media for data backup, and they are different from each other in usage:
