* TODO Backer Tasks

** DONE Consider different compression algorithms
   - [X] 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. 
   - [X] Implemented bzip2 as alternative (pure Go, via github.com/dsnet/compress)
   - [X] Implemented zstd as alternative (pure Go, via github.com/klauspost/compress/zstd)
   - [X] Add compression_algorithm config option
   - Note: xz and lz4 can be added later if needed (pure Go libs available)

** DONE Configurable filename prefix
   - [X] Move "backup" prefix to config (currently hardcoded in newServer.go)
   - [X] Default: "backup", e.g., "backup-20260325-092341.tar.gz"
