Backups Without Compromise

Platforms: Windows, Linux (macOS coming soon)

Overview

Relica 2.0.0 is a major release delivering faster performance, a completely redesigned interface, and an improved user experience. Whether you're backing up to the cloud or a local NAS, everything is faster, smoother, and more intuitive.

What's New

Significantly Faster Backups

We've rebuilt Relica's backup engine for speed across all scenarios:

Operation Improvement
Cloud backups Up to 80% faster
Local/NAS backups Up to 40% faster
Restores Up to 60% faster
Memory usage 20-40% reduction

Smarter Compression

Relica 2.0.0 includes improved compression that reduces your cloud storage costs:

  • Better compression ratios — store more data in less space
  • Faster compression — no longer a bottleneck during backups
  • Automatic optimization — Relica chooses the best settings for your data

The result: lower monthly storage bills without any extra configuration.

Redesigned Interface

A completely modernized look with a premium dark theme:

  • Dark theme throughout — easier on the eyes, especially for overnight backups
  • Cleaner layouts — focus on what matters
  • Improved status indicators — instantly see backup health at a glance

Enhanced Backup Dashboard

The new dashboard gives you a complete picture of your backup status:

  • At-a-glance health overview — see all your backups in one place
  • Storage usage breakdown — understand where your space is going
  • Recent activity timeline — track what's been backed up
  • Quick actions — run, pause, or configure backups with one click

Setup Wizard

New users get a guided experience to configure their first backup:

  • Step-by-step setup — no guesswork required
  • Source selection — easily pick folders to back up
  • Destination guidance — choose cloud, local, or both
  • Schedule configuration — set it and forget it

Existing users can also use the wizard to create additional backups.

Real-Time Progress Tracking

See exactly what's happening during your backups:

  • Live progress bar with percentage complete
  • File counter: "Processing file 4,567 of 10,000"
  • Data transferred: "9.0 GB / 20.0 GB"
  • Transfer speed: "87.3 MB/s"
  • Time remaining: "2m 34s"
  • Current file being backed up

Updates appear instantly — no more waiting to see if your backup is running.

Smarter CPU Management

Relica now handles resources more intelligently:

  • No throttling on manual backups — when you click "Run Now," Relica uses full speed to finish as quickly as possible
  • 50% CPU limit for scheduled backups — background backups won't slow down your computer while you work
  • Configurable throttling coming soon — future builds will let you customize these settings

Expanded Cloud Storage Support

  • Cloudflare R2 — S3-compatible with no egress fees
  • Enhanced Backblaze B2 — improved native API support
  • More S3-compatible providers — expanded compatibility
