545183efda- quickstart: no segments in borg2 (packs/unreferenced-objects wording); backend list is file:/rest: plus sftp/s3/b2; fix the example script's exit-code handling for BORG_EXIT_CODES=modern (highest-rc-wins ranked warnings 100..127 above errors 3..99 and the rc==1 warning branch was dead) with a severity classifier; regenerate the --stats and repo-list samples from real runs; make the prose repo path match the script's rest:// URL; typos; correct the repository model description (no manifest tracking blocks). - repository-urls: use rest:// in the BORG_REPO example (ssh:// is legacy-only, as the same file says). - file-systems: rewrite for packs (chunks are grouped into pack files of up to ~50 MB; compact works at pack granularity). - resources: borg repo-delete (not "delete repo", not server-side); replace the false "single-threaded, max 100% of one core" claim with the real multi-threaded cases (zstd, blake3, pack writer). - positional-arguments: drop borg1 repo::archive wording. - config: fix the --print_config example (must precede the subcommand) and the related prose. - usage_general.rst.inc (man intro): add the archive-specification and config includes that were only added to the usage variant when the two files diverged (oversight from the #4587 split; the archive-specification include uses :start-after: to avoid a duplicate label). - fix dead links: IEC binary prefixes (wikipedia anchor moved), paperkey.html in the borg 1.x changelog. - misc: update benchmark-crud commands to borg2 (with a note that the numbers are borg1-era); add a preamble to create_chunker-params noting it predates borg2/fastcdc.

borg benchmark crud
|
|
===================
|
|
|
|
Here is an example of borg benchmark crud output.
|
|
|
|
Note: these measurements were made with borg 1.x and are kept for historical
|
|
reference. The commands below are updated to borg 2 syntax, but the numbers
|
|
were NOT re-measured with borg 2.
|
|
|
|
I ran it on my laptop: Core i5-4200U, 8 GB RAM, SATA SSD, Linux, ext4 filesystem.
|
|
"src" as well as repo is local, on this SSD.

|
|
|
$ BORG_PASSPHRASE=secret borg -r repo repo-create --encryption aes256-ocb --id-hash blake3 --key-location repokey
|
|
$ BORG_PASSPHRASE=secret borg -r repo benchmark crud src
