How to choose
If you manage multiple devices, iDrive's single-account model for multiple PCs and NAS devices is more cost-effective than Backblaze's per-computer license ($9/month per computer).
For Synology or QNAP users, budget an additional $40 per TB per year for iDrive NAS integrations, or choose Backblaze if NAS backup is not required.
Choose Acronis True Image (from $49.99/year) if you need bare-metal recovery to different hardware; choose Backblaze or Carbonite for simple file-level restoration.
Backblaze and Livedrive offer effectively unlimited storage for their base plans, whereas iDrive caps storage at 5 TB for its $11.99/month tier.
