ASSERTs still dump stack traces to the console and file in all cases. ERRORs only dump stack traces to the file when the file log level is DEBUG or TRACE.
* Better resume support. Resumed files are checked to be sure they have not been modified and the manifest is saved more often to preserve checksums as the backup progresses. More unit tests to verify each resume case.
* Resume is now optional. Use the `resume` setting or `--no-resume` from the command line to disable.
* More info messages during restore. Previously, most of the restore messages were debug level so not a lot was output in the log.
* Fixed an issue where an absolute path was not written into recovery.conf when the restore was run with a relative path.
* Added `tablespace` setting to allow tablespaces to be restored into the `pg_tblspc` path. This produces compact restores that are convenient for development, staging, etc. Currently these restores cannot be backed up as PgBackRest expects only links in the `pg_tblspc` path.
1) Re-checksums files that have checksums in the manifest
2) Recopies files that do not have a checksum
3) Saves the manifest at regular intervals to preserve checksums
4) Unit tests for all cases (that I can think of)
* Fixed a buffering error that could occur on large, highly-compressible files when copying to an uncompressed remote destination. The error was detected in the decompression code and resulted in a failed backup rather than corruption so it should not affect successful backups made with previous versions.
* Pushing duplicate WAL now generates an error. This worked before only if checksums were disabled.
* Database System IDs are used to make sure that all WAL in an archive matches up. This should help prevent misconfigurations that send WAL from multiple clusters to the same archive.
* Regression tests working back to PostgreSQL 8.3.
* Improved threading model by starting threads early and terminating them late.
All tests local over SSH with rsync default compression, 4 threads and default compression on backrest. Backrest default is gzip = 6, assuming rsync is the same.
On a 1GB DB:
rsync time = 32.82
backrest time = 19.48
backrest is 171% faster.
On a 5GB DB:
rsync time = 171.16
backrest time = 86.97
backrest is 196% faster.
Moved Remote code from pg_backrest.pl to Config.pm.
Added version specific code to regression tests and Db.pm.
archive-push checks for duplicate WAL in the archive.
archive-push reads the db sys id to match up WAL to the correct archive.
