Proxmox Backup Server
Deduplication, incremental copies and verification — the same volume takes far less space.

Proxmox Backup Server and a recovery plan
A backup is not what gets created — it is what gets restored. I deploy PBS, write the recovery plan and test it monthly, so that at moment X everything really comes back.

Backup / capabilities
What it covers
A 3-2-1 strategy, deduplication, incremental copies and an offsite copy on S3 — in one manageable system.
VMs, LXC and files
A whole VM, a container or a single folder — from one panel, on one schedule.
Offsite copy
A second PBS at another site or an S3 bucket remotely — fire, theft or ransomware cannot kill everything at once.
Schedule and retention
Daily, weekly and monthly copies — with retention periods set in writing.
Restore testing
Every month I restore a real copy into a separate environment and record the time — that is the real guarantee.
Documentation
What is stored where, how it is restored and who has access — in writing, not in someone’s head.
process
How the process runs
-
01
Inventory
What data exists, what is critical and what loss is acceptable.
-
02
Strategy
RPO and RTO — how much data may be lost and how fast it must come back.
-
03
Build
PBS, storage, schedule, offsite replication and access control.
-
04
Test
A restore rehearsal and a report — before you actually need it.
cases
Examples
After ransomware
An encrypted server was restored from the previous day’s copy — operations resumed the same day.
12 TB archive offsite
Thanks to deduplication, 12 TB is kept offsite at a reasonable cost.
faq
Common questions
How often are backups taken?
Daily by default, every 6 hours for critical systems. The schedule matches your rhythm.
Where is the offsite copy kept?
At a second site or in an S3 bucket, encrypted. The key stays with you.
How fast does a server come back?
A small VM takes 10–20 minutes, a large system 1–2 hours. The exact figure is recorded after testing.

Do you know how fast your server would come back?
If you do not know — that is exactly why it is worth fixing. Let us start with an audit.
