Configuring the New Tool

このセクションでは、3つのツールの比較を行い、設定（config ファイル）とスケジューリングの違いを示します。移行中は、これらの違いをすべて認識し、必要に応じて変更を適用することが重要です。

機能の設定方法

次のセクションでは、実装の詳細を簡単に比較できるように、さまざまなツールで機能を有効にする方法について説明します。

• Postgres connection details

• Use of direct file copy mode (ssh or rsync) instead of pg_basebackup

• Incremental backups

• WAL archive compression

• Backup compression

• Parallel backup and restore

• Retention Policy

• Configure repository location

Postgres接続の詳細

Tool	Configuration
BART	In the [SERVER] section of the config file: [e xample]…host = localhostuser = postgres port = 5432
Barman	In the config file: [example]…conn info = host=localhost user=postgres dbname=postgres
pg BackRest[^*]	In the config file: [example]…pg1 -host = localhostpg1-path = /var/lib/postgres /datapg1-user = postgresport = 5432

pgBackRestがローカルで実行されている場合はpg1- パスを指定し、 pgBackRestがリモートで実行されている場合はpg1- ホストを指定します

pg_basebackupの代わりに直接ファイルコピーモード（sshまたはrsync）を使用

Tool	Configuration
BART	Increase threads >1 in the [SERVER] or [BART] section of the config file:[example]…thread_count = 2Or, as a commandline option --no-pg_basebackup
Barman	In the config file: [example]…backup_method = rsync
pgBackRest	pgBackRest does not support pg_basebackup option

増分バックアップ

Tool	Configuration
BART	Retrieve the backup_id or backup_name for the parent:bart SHOW-BACKUPS exampleNow supply he backup_id or backup_name as parent:bart BACK UP –s example --parent { backup_id \| backup_name }
Barman	In the config file:[example]…reuse_backup = linkOr, as a command line option:--reuse-backup=link
pgBackRest	pgbackrest --stanza=example --type=incr backup

WALアーカイブ圧縮**

Tool	Configuration
BART	In the [SERVER] or [BART] section of the config file: [example]…wal_compression = enabled
Barman	In the config file:[example]…compression = gzip
pgBackRest	Global compress settings. Can be overloaded for [global:archive-push]

バックアップ圧縮

Tool	Configuration
BART	Command line option: Enable: --gzipLevel: --compress-level
Barman	N/A
pgBackRest	compress=ycompress-level=9compress-type=gzcompress-level-network=3

並列バックアップと復元

Tool	Configuration
BART	Set thread_cound in the [SERVER] or [BART] section of the config file: [example]…thread_count = 4Or, as a Command line option --thread-count=4
Barman	Set parallel_jobs in the configfile:[example]…parallel_jobs = 4Or, as a command line option --jobs 4
pgBackRest	Set process-max in the configfile:[example]…process-max = 4Or, as a command line option --process-max=4

保持ポリシー

Tool	Configuration
BART	Set retention_policy in the [SERVER] or [BART] section of the config file:[example]…retention_policy = 2 BACKUPS # Or DAYS, WEEKS, or MONTHS
Barman	Set retention_policy, and/or wal_retention_policy options in the config file:[example]…retention_policy =REDUNDANCY 2 orretention_policy = RECOVERY WINDOW OF 2 DAYS # WEEKS/MONTHS.
pgBackRest	Can be set in the config file:[example]…repo -retention-full-type = count #can also be time`` repo-retention-full = 2````repo-retention-diff = 6 ````# Retain WAL archives for only 1 full backup:` ```repo-retention-archive-type = full #can also be diff or incr``repo-retention-archive = 1See Retention Policy in edb documentation for more information.

リポジトリの場所を設定する

Tool	Configuration
BART	In the config file in the [BART] section:[BART]…backup_path = /tmp/bart
Barman	In the config file in the main chapter:backup_directory = /tmp/barman
pgBackRest	[global]repo1-path=/var/lib/pgbackrest
