Polenta RoboCopy and rsync Simplified

Description

PRRS is a free command-line file sync utility that brings together the practical strengths of Microsoft Robocopy and Linux rsync—with options that stay simple: one flag, one idea. Mirror, update, exclude, checksum, size/date filters, parallel workers, retries, progress and logging.

Platform: Windows 10/11 (x64) and Linux (amd64)
License: Freeware
Version: 1.2.0

Features

Simple sync
PRRS <source> <destination> copies directory contents into the destination (Robocopy / rsync src/ style).
Mirror (-m)
Copy, then delete destination extras. One switch—not a stack of Robocopy flags.
Update (-u)
Never overwrite a newer destination file.
Exclude (-x)
Skip files and folders with repeatable patterns: -x *.tmp -x .git.
Checksum (-c)
Compare SHA-256 content instead of size and time only.
Filters
--min-size / --max-size (10K, 2M) and --after / --before (YYYY-MM-DD or 7d).
Parallel & resilient
-w workers (default 4), --retries, -p progress, -l log file.
Cross-platform
Same CLI on Windows and Linux. Dry-run with -n before you write.

Usage

PRRS <source> <destination> [options]

Examples

            PRRS C:\Data\Photos D:\Backup\Photos

            Sync a folder tree

            PRRS .\src .\dst -m -x *.tmp -x .git

            Mirror with excludes

            PRRS .\src .\dst --after 7d --min-size 1K -w 8 -l sync.log

            Recent files only, parallel copy, log to file

            PRRS /home/user/docs /mnt/backup/docs -u -c

            Linux: update mode with content checksum

            PRRS .\src .\dst -n
