Parcours stack : Nexcess S3 Multisite Backup

This stack guide covers nexcess s3 multisite backup as a concrete Multisite operations path. Combine hosting-class limits (PHP time/memory, cron, disk) with Multisite Migrate’s Jobs in Chunks and the correct destination: native Plus targets are Google Drive, Dropbox, S3-compatible storage, and SFTP.

Wasabi, Backblaze B2, Cloudflare R2, DigitalOcean Spaces, and MinIO are used through S3-compatible endpoints — not as separate proprietary vaults. Free keeps local schedules; Plus adds cloud schedules and upload; Pro adds remote import, empty-server installer, Staging, and network split/extract. For migrations between hosts, take a verified archive first, move with the matching restore path, then confirm URLs, media, and users on Staging before DNS cutover. Tier focus: Plus. Keep the previous host reachable until the new Staging drill passes twice, and document which Plus destination holds the rollback object so on-call staff are not hunting buckets during an outage.

Contraintes hôte et jobs en chunks

For nexcess s3 multisite backup, prepare PHP limits, real cron where wp-cron is delayed, and free disk for Multisite-sized archives. Jobs in Chunks resume after interrupts so host timeouts do not force a full restart.

Exclude cache/tmp noise. Confirm Network Admin vs subsite scope before the first production schedule.

Vérité des destinations pour ce stack

Connect Plus destinations you actually have: Google Drive, Dropbox, S3-compatible, or SFTP. Test the connection with a small job before relying on overnight schedules. OneDrive is not native. S3-compatible services share endpoint/credential patterns — label them clearly in ops docs.

Retention: keep enough generations for rollback. A stack named “Nexcess S3 Multisite Backup” still fails if you only keep one corrupt overnight object.

Migration et cutover

Archive → transfer → restore → verify before DNS cutover. Use import, remote import, or empty-server flows as your tier allows. Staging is the place to catch HTTPS, mapping, and media issues — not the live cutover window.

If moving between hosts, keep the old archive until the new Staging drill passes twice.

Rétention, chiffrement et hygiène support

For nexcess s3 multisite backup, 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.

When opening a support ticket, include the last job log lines, hosting class, PHP limits, free disk, and whether a local archive already exists.

Décisions liées souvent oubliées

For nexcess s3 multisite backup, decide schedule windows that avoid peak traffic, who owns Network Admin credentials, and how long local plus offsite copies are retained. Align Free local schedules with Plus cloud upload only after a Staging restore has passed.

Also record whether the job is full-network or include/exclude subsites. That single choice prevents most “backup succeeded but site missing” surprises after a restore drill.
