Question by : Virtual Tape Library or Tapes Drives?
I was wondering if anyone still used tapes to backup their servers. I’m currently looking into a VTL (Virtual Tape Library) but I didn’t know if it was worth it or if I should buy cloud hosting.
Answer by Charles
Tape, VTL or cloud it will largely come down to the financial analysis. Tape continues to be the most cost effective over the long term since tape systems are typically not replaced as frequently as disk systems (VTLs are disk based systems) and a tape cartridge doesn’t require much power or cooling when sitting in a rack/library. VTLs may offer advantages that could speed up your backups (many mount points), speed recoveries and coupled with deduplication technology and off-site replication more than meet your needs. The costs will be significantly higher compared to tape…but it is up to you to determine if the additional features are worth the expense. When you say cloud hosting are moving primary and backup data to the cloud or just backup data? There are many challenges with either approach starting with bandwidth and the potential costs to obtain enough bandwidth so you can meet your throughput needs. Backup would be less bandwidth sensitive so long as you have enough to meet backup windows.
