Overview of Backup Storage Media

Z-DBackup can back up data to any target drive that has a drive letter or UNC path. On this page, we give you an overview about the features and pros and cons of several popular storage mediums to help you choose the right one for your environment.

Backup to Hard Disk

  • A backup to an internal hard drive is still better than none at all.

  • Simple and fast

  • Considerations: Fixed internal hard drives are vulnerable to anything which might destroy your original data – physical damage, fire, water, overvoltage, theft etc.

  • In a case of emergency, you lose your backups along with your original data, and might be faced with devastating consequences! Therefore, only use external hard drives.


Backup to External USB Hard Disc

  • Small, light and robust

  • Simple and fast

  • Considerations:

    • Who has access to the data?

    • Use a backup encryption with a secure password!

    • How is the external drive protected from outside influences?


Backup to USB Flash Drive

  • By now a cost-effective, interesting alternative

  • Usable just like a normal drive

  • However, not suitable as the only backup method!

  • Very small, that makes it practical for transporting, but implies a higher risk of loss.

  • Considerations:

    • Who has access to the data?

    • Use a backup encryption with a secure password!


Backup to Removable Hard Drive

  • If you install a removable hard disk drawer in your company and also in your home, you can just take the hard drive from the office home with you, and vice-versa.

  • If you only use the exchangeable hard disk, you still need another backup medium.


Backup to Tapes

According to a survey by Symantec, 64 % of IT professionals rely exclusively on tape backups, but interestingly, another 32,5 % of respondents combine tape and hard disc backups.

  • Easy with our add-on module Z-DATdump for tape drives (TRAVAN, DAT, QIC, MLR, AIT, LTO, DLT, VXA, DDS, SLR)
