Time Machine–style rsync snapshots for Linux — hardlinked and space-cheap https://git.cjennings.net/rsyncshot/atom?h=main 2026-06-25T16:04:58+00:00 2026-06-25T16:04:58+00:00 Craig Jennings c@cjennings.net 2026-06-25T16:04:58+00:00 urn:sha1:e44391ed2422dcc759c9e5972bfd3aecf8216e26 2026-06-25T05:07:31+00:00 Craig Jennings c@cjennings.net 2026-06-25T05:07:31+00:00 urn:sha1:03a9ff353721ba8fb5f37cad2546d25788011451 Refuse to run when REMOTE_PATH or MOUNTDIR is empty or non-absolute. A blank config value otherwise resolves the destination to the filesystem root, where rotation runs rm -rf and --delete. Run the rotation cp/mv/rm as bare command names in remote mode, resolved by the remote PATH, instead of hardcoded /usr/bin paths that broke on remotes whose binaries live elsewhere. Resolve the real binary via command -v in local mode. Pass rsync -R so each source is stored under its full path. Two includes sharing a basename (/usr/local/bin and /usr/bin) previously both mapped to latest/bin, and the second sync's --delete wiped the first. This changes the stored layout: /usr/local/bin now lives at latest/usr/local/bin instead of latest/bin. /home and /etc are unchanged. Add rsync --numeric-ids so /etc and /home ownership survives a restore when the destination has a different passwd/group database. Match mount points exactly via is_mounted() instead of a substring grep of /proc/mounts, so /media/backup no longer matches /media/backup2, paths compare literally, and mount points with spaces work. Reject a retention count below 1, which previously still created one snapshot. Drop the grep "|| echo 0" that emitted a stray second line, assemble ssh options as arrays, and quote the RSYNC_RSH identity path. Extract derive_paths() and is_mounted() as sourceable functions and add unit, rsync-flag, and gated remote-mode test suites. The suite now runs 36 tests, and shellcheck is clean across the script and tests. 2026-04-20T13:36:28+00:00 Craig Jennings c@cjennings.net 2026-04-20T13:36:28+00:00 urn:sha1:2e895830798d1685c35f24e595896b5caa4fdbcc Per claude-templates c36fd14.

Increase rsync --timeout from 300s to 600s for slower connections.
