如何在 TMDHosting 上正确做 Multisite 备份
On TMDHosting (shared 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. PHP max_execution_time and memory ceilings are often tight on shared plans.
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. Inode and tmp-disk limits can abort oversized archives mid-job.
在 TMDHosting 上完整 Multisite 备份必须包含什么
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 TMDHosting creates “successful” archives that still fail a real restore drill. Exclude cache, tmp, and other regenerable noise so jobs finish faster on shared plans.
WordPress cron may be delayed unless a real system cron hits wp-cron.php. 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 TMDHosting control panel.
Multisite Migrate 如何在此类主机上运行任务
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 TMDHosting, 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.
TMDHosting 恢复演练清单
Before you trust a TMDHosting 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 TMDHosting, check locks, tmp cleanup, and whether a new job ID was created before re-running.
保留、加密与支持卫生
For wordpress multisite backup on tmdhosting, 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.

TMDHosting 快照对 Multisite 够用吗？?
Multisite Migrate 答复：Free/Plus/Pro、分块任务、自带云与 Staging 恢复演练。
子站点管理员能否只备份自己的站点？?
可以。子站点具备 manage_options 时，Free 可做站点级备份/恢复。
哪些云目标可用？?
Plus 支持 Google Drive、Dropbox、S3 兼容端点与 SFTP——没有专有 Multisite Migrate 保险库。
问题：What usually breaks Multisite backups on shared hosts?
限额提到够用即可，仍用分块任务——共享主机仍可能杀掉长进程。
