Back Up 3CX to Any S3-Compatible Storage, Not Just Amazon
Controvo Backup Manager sends 3CX backups to Wasabi, Backblaze B2 and other S3-compatible providers, confirms every backup, and shows what each customer uses, across every phone system you manage.
What Backup Manager Does
Backup Manager is the 3CX backup tool in Controvo. Connect a storage provider once, choose the phone systems that use it, and 3CX backups from every customer land in the storage you picked. You choose the vendor, the price and the region instead of taking a default.
It also confirms each backup, prunes old backups with advanced retention policies, and breaks storage usage out per customer.

Back Up 3CX to the Provider You Already Use
Back up 3CX to Wasabi
Wasabi is a popular low-cost object storage choice for backups, and one we have validated with real 3CX backups. Connect Wasabi once in Backup Manager and choose the customers and phone systems that use it.
Back up 3CX to Backblaze B2
Backblaze B2 is validated with real 3CX backups. Add it as a storage connection, match its buckets to your customers, and see usage per customer afterward.
Back up 3CX to Hetzner, OVHcloud or Scaleway
European providers are on the list for partners who want backups kept in-region. Pick the provider and region that fit the customer, and use it for that customer’s systems.
Back up 3CX to DigitalOcean Spaces, Vultr or Akamai (Linode)
If your team already runs infrastructure on one of these, your 3CX backups can sit beside it instead of with another vendor.
Back up 3CX to Seagate Lyve Cloud, PeaSoup Cloud or Amazon S3
Lyve Cloud and Amazon S3 work with full usage reporting. PeaSoup Cloud works in a 3CX-backups-only mode that needs no read key.

Fleet-Wide Setup
Connect once and choose the systems that use it, across customers, with live progress for each one.

Every backup shows Confirmed, or Failed with the reason 3CX gave. Updates can back up first and wait for confirmation.
Advanced Retention Policies
Clean Up deletes by age, keeps the newest few, and can keep the newest of each 3CX version. Preview every Delete and Keep first, then schedule it.
Usage Per Customer
See what each customer uses, matched to their phone systems, so you can price backup storage and spot the heavy user.
Growth Projection
A storage growth chart with recorded history and a 90-day projection, so the next bill is not a surprise.
3CX Backup Manager FAQs
Can 3CX back up to storage that is not Amazon S3?
Yes, with Controvo. Backup Manager sends 3CX backups to S3-compatible object storage such as Wasabi, Backblaze B2, DigitalOcean Spaces, Hetzner, OVHcloud, Scaleway, Seagate Lyve Cloud, Vultr and Akamai (Linode), as well as Amazon S3.
Can I back up 3CX to Wasabi?
Yes. Wasabi is one of the providers we have validated with real 3CX backups. You add a Wasabi connection once in Backup Manager and choose the phone systems that use it.
Can I back up 3CX to Backblaze B2?
Yes. Backblaze B2 is validated with real 3CX backups. Add it as a storage connection in Backup Manager, then choose the systems that use it.
Do I have to set this up on every 3CX system separately?
No. You set up the storage connection once and choose the phone systems that use it, across customers. Controvo shows the progress for each system.
How do I know a 3CX backup actually worked?
Backup Manager tracks every backup it runs until the phone system confirms it. Each job shows Confirmed, or Failed with the reason 3CX gave. Update Manager can also back up first and only install an update after the backup is confirmed.
Can I automatically delete old 3CX backups?
Yes. Clean Up applies advanced retention policies: delete backups older than a number of days, always keep the newest few, and optionally keep the newest backup of each 3CX version. You preview exactly what is deleted and kept before it runs, then schedule it to repeat.
Can I see how much backup storage each customer uses?
Yes. Once storage is connected, Backup Manager shows usage per customer, matched to the phone systems you manage, with a growth chart and a 90-day projection.
Does Controvo need a key to read my storage?
Only if you want usage reporting. A 3CX-backups-only mode sends backups to the provider without giving Controvo a read key. It is used for providers Controvo cannot report on yet, such as PeaSoup Cloud.
Can I keep a customer’s backups in a specific country?
Choosing the storage provider and region is the first step. Pick a provider with storage in the country you need and use it for that customer’s systems.
Which S3-compatible providers work?
The providers listed on this page are built into Backup Manager. Other S3-compatible storage can work too. Contact us with the provider you want.
