Script Review: 0001-transfer.sh

Purpose: Creates a compressed backup image of an NTFS partition using partclone and zstd compression.

Key Components:

• Source: /dev/nvme0n1p2 (NTFS partition)
• Output: /x/sata1/snapshots/nvme-old-1tb.zst (compressed image)
• Transfer Size: 436G (used for progress monitoring)

Pipeline:

1. partclone.ntfs -c -s $SOURCE_DISK -o - - Clones NTFS partition to stdout
2. pv -s $TRANSFER_SIZE -pterb - Monitors progress with visual feedback (progress, time, rate, bytes)
3. zstd -T0 -19 -o $OUTPUT_IMAGE_PATH - Compresses with max compression (level 19) using all CPU threads

Notes:

• Requires sudo privileges
• Uses maximum compression (-19) for best space efficiency
• Multi-threaded compression (-T0) for faster processing
• Progress bar provides real-time feedback during the long-running operation

Let's go.
