From 88dba54087e658633f12f1bb49547194dbf04efa Mon Sep 17 00:00:00 2001 From: Wendell Jones Date: Mon, 23 Feb 2026 18:31:27 -0500 Subject: [PATCH] Add user-configurable PostgreSQL backup system Introduced backup/restore via external pg_dump/pg_restore tools, configurable in database.xml. Added DatabaseBackupOptions, PostgresBackupService, and example/config docs. Backup features are enabled only for local databases; remote DBs require manual management. Logging and documentation clarify external tool usage, error handling, and security. Updated provider logic and assembly files accordingly. --- .../PublishProfiles/FolderProfile.pubxml.user | 2 +- POSTGRES_BACKUP_IMPLEMENTATION.md | 200 ++++++++ POSTGRES_BACKUP_LOCAL_ONLY_IMPLEMENTATION.md | 235 +++++++++ POSTGRES_BACKUP_LOGGING_EXTERNAL_TOOLS.md | 167 ++++++ .../netstandard2.0/Jellyfin.CodeAnalysis.dll | Bin 8704 -> 8704 bytes .../netstandard2.0/Jellyfin.CodeAnalysis.pdb | Bin 10220 -> 10220 bytes .../Jellyfin.CodeAnalysis.AssemblyInfo.cs | 2 +- ...yfin.CodeAnalysis.AssemblyInfoInputs.cache | 2 +- .../netstandard2.0/Jellyfin.CodeAnalysis.dll | Bin 8704 -> 8704 bytes .../netstandard2.0/Jellyfin.CodeAnalysis.pdb | Bin 10220 -> 10220 bytes .../DbConfiguration/DatabaseBackupOptions.cs | 75 +++ .../DatabaseConfigurationOptions.cs | 7 +- .../DbConfiguration/database.xml.example | 73 +++ .../BACKUP_CONFIGURATION.md | 258 ++++++++++ .../PostgresBackupService.cs | 481 ++++++++++++++++++ .../PostgresDatabaseProvider.cs | 149 +++++- 16 files changed, 1637 insertions(+), 14 deletions(-) create mode 100644 POSTGRES_BACKUP_IMPLEMENTATION.md create mode 100644 POSTGRES_BACKUP_LOCAL_ONLY_IMPLEMENTATION.md create mode 100644 POSTGRES_BACKUP_LOGGING_EXTERNAL_TOOLS.md create mode 100644 src/Jellyfin.Database/Jellyfin.Database.Implementations/DbConfiguration/DatabaseBackupOptions.cs create mode 100644 src/Jellyfin.Database/Jellyfin.Database.Implementations/DbConfiguration/database.xml.example create mode 100644 src/Jellyfin.Database/Jellyfin.Database.Providers.Postgres/BACKUP_CONFIGURATION.md create mode 100644 src/Jellyfin.Database/Jellyfin.Database.Providers.Postgres/PostgresBackupService.cs diff --git a/Jellyfin.Server/Properties/PublishProfiles/FolderProfile.pubxml.user b/Jellyfin.Server/Properties/PublishProfiles/FolderProfile.pubxml.user index e6ccac0f..d6e5c069 100644 --- a/Jellyfin.Server/Properties/PublishProfiles/FolderProfile.pubxml.user +++ b/Jellyfin.Server/Properties/PublishProfiles/FolderProfile.pubxml.user @@ -3,7 +3,7 @@ <_PublishTargetUrl>E:\Program Files\Jellyfin - True|2026-02-23T22:50:19.2488617Z||;True|2026-02-23T17:40:34.7963081-05:00||;True|2026-02-23T17:30:42.0185573-05:00||;False|2026-02-23T16:44:17.4036787-05:00||;False|2026-02-23T16:10:39.9498056-05:00||;False|2026-02-23T16:06:47.9500254-05:00||;True|2026-02-23T15:36:20.8511403-05:00||;True|2026-02-23T14:06:04.7110322-05:00||;True|2026-02-23T13:51:39.0686004-05:00||;True|2026-02-23T13:12:08.3890386-05:00||;False|2026-02-23T13:06:12.0188266-05:00||;True|2026-02-23T12:08:36.6307546-05:00||;False|2026-02-23T12:02:39.0223565-05:00||;True|2026-02-23T11:48:21.1980918-05:00||;True|2026-02-23T11:13:01.1928466-05:00||;True|2026-02-23T10:32:13.7989634-05:00||;True|2026-02-23T09:02:53.5227868-05:00||;True|2026-02-23T08:11:05.7403694-05:00||;False|2026-02-23T08:07:46.6244256-05:00||;True|2026-02-23T08:00:05.0454829-05:00||;False|2026-02-23T07:56:44.6461434-05:00||;True|2026-02-23T07:50:44.1212024-05:00||;True|2026-02-23T07:29:19.3226285-05:00||;True|2026-02-22T20:02:08.7802640-05:00||;True|2026-02-22T19:00:49.1033285-05:00||;True|2026-02-22T18:46:50.8399883-05:00||;True|2026-02-22T18:36:34.2983199-05:00||;True|2026-02-22T18:33:05.9495883-05:00||;True|2026-02-22T18:28:09.3531365-05:00||;True|2026-02-22T18:23:19.7767548-05:00||;True|2026-02-22T18:03:49.9702878-05:00||;True|2026-02-22T17:31:43.8027839-05:00||;True|2026-02-22T17:14:22.1722691-05:00||;True|2026-02-22T17:07:09.6937759-05:00||;True|2026-02-22T16:29:37.5643134-05:00||;True|2026-02-22T16:05:05.3412117-05:00||;True|2026-02-22T15:59:39.7645693-05:00||;
