IONOS VPS での WordPress Multisite バックアップ

IONOS VPS で Multisite バックアップを正しく行う

On IONOS VPS (vps hosting), a WordPress Multisite backup is more than copying wp-content. You need shared core files, network tables, per-site tables, and uploads under sites/ — or restore will miss users, settings, or media. You control PHP-FPM and Nginx/Apache timeouts — raise them, then still use chunked jobs.

Multisite Migrate runs chunked, resumable jobs from Network Admin (full network) or from a subsite dashboard when the role has manage_options. Free covers core network/subsite backup and restore plus one local schedule. Plus adds BYO cloud upload (Google Drive, Dropbox, S3-compatible, SFTP) and cloud schedules. Pro adds remote import, empty-server installer, Staging, WP-CLI, and network split. Object storage or SFTP offsite pairs well with local schedules.

Capture the network tables (wp_blogs, wp_site, wp_sitemeta, and related), each subsite’s tables, shared themes/plugins, and the sites/ upload tree. Skipping any of those on IONOS VPS creates “successful” archives that still fail a real restore drill. Exclude cache, tmp, and other regenerable noise so jobs finish faster on vps plans.

Disk I/O spikes during full network archives; schedule off-peak windows. Treat provider snapshots as an extra layer — not a Multisite-scoped import workflow. Keep a plugin archive you can move, import, and verify independently of the IONOS VPS control panel.

このホストクラスでの Multisite Migrate の実行方法

Shared and managed hosts often kill long PHP workers. Multisite Migrate therefore uses Jobs in Chunks that resume instead of restarting from zero after a timeout. On IONOS VPS, start from Network Admin for fleet backups, or from a single site when a subsite admin only needs their site. Watch the job log for the last completed chunk, disk/inode warnings, and cloud auth errors on Plus.

For schedules: Free keeps one local schedule; Plus can push finished archives to Drive, Dropbox, S3-compatible storage, or SFTP. Wasabi, Backblaze B2, Cloudflare R2, DigitalOcean Spaces, and MinIO are S3-compatible endpoints — not separate proprietary vaults. OneDrive is not a native destination.

IONOS VPS 向けリストア演習チェックリスト

Before you trust a IONOS VPS backup routine, restore once on Staging (or a throwaway site): check siteurl/home, HTTPS, domain mapping (sunrise.php if used), media under sites/, logins, and any WooCommerce or membership data. Confirm rewrite rules and purge CDN/object-cache drop-ins if the front end still shows stale content.

If a job restarts at 0% on IONOS VPS, check locks, tmp cleanup, and whether a new job ID was created before re-running.

保持・暗号化・サポート衛生

For wordpress multisite backup on ionos vps, keep enough archive generations to roll back a bad deploy or failed migration. Optional .venc AES-256 encryption on Multisite Migrate archives protects copies at rest when you store offsite on Plus destinations. Document credentials, schedule windows, and who may run Network Admin jobs.

Separate schedule failures from restore failures in your runbook so on-call staff do not rebuild a finished archive unnecessarily.
