TODO Backer Tasks

DONE Consider different compression algorithms

• Evaluate alternatives to gzip: bz2, xz, lzo, lz4
• CANCELLED lzo. It has cgo implementaion which depends in liblzo, and native lid that does not support streaming.
• Implemented bzip2 as alternative (pure Go, via github.com/dsnet/compress)
• Implemented zstd as alternative (pure Go, via github.com/klauspost/compress/zstd)
• Implemented lz4 as alternative (pure Go, via github.com/pierrec/lz4)
• Implemented xz as alternative (pure Go, via github.com/ulikunitz/xz)
• Add compression_algorithm config option

DONE Configurable filename prefix

• Move "backup" prefix to config (currently hardcoded in newServer.go)
• Default: "backup", e.g., "backup-20260325-092341.tar.gz"
