Last Line of Defense: be prepared by Open
Source Backups with Bareos

Bareos is a registered trademark of Bareos GmbH & Co. KG
Agenda
●
Resilience and Disaster recovery in times of
Ransomware
●
Why Open Source Backups are crucial
●
Overview: Bareos – the Open Source backup
solution

Threats
●
Known threats and data loss
– Physical damage
– Software failure
– User failure: rm -Rf /
– Malware / Ransomware
– Intrusion
– ...
●
Unknown / unexpected threats ?
– ...

Defense and Recovery
●
Important but scope for other talks
– DMZ / Firewalls
– Virus scanners
– Intrusion detection
– Training to prevent social engineering
●
Our subject
– Resilience and disaster recovery
●
Our daily routine is the unexpected
William T. Riker

Sidekick: Non-Data Backups
●
Svalbard Global Seed Vault
●
Statistics ~860k seed types
●
Funded by Norwegian government
●
Backup of global seeds to ensure
nutrition after big catastrophes
●
First Use-Case: Syria 2015
– Research center Icarda (Aleppo)
not fully functional
– Restore / re-cultivate lentil seeds
from backup seed in new location

Some Backup Guidelines
●
Network backup: copy your data to dedicated backup
server
●
Backup your backup: make replication to other media
/ sites.
●
Backup to cloud: encryption mandatory
●
Plan your backup and retention:
– How long do you need to retain your backup data?

Be prepared against Ransomware
●
Protect your backup data
– Backups to disk: separate from rest of network,
only allow access for backup protocol
– Read-only medium (worm-tape)
●
If using backup-data encryption
– Extra copy of encryption key – if lost or unreadable
due to ransomware attack – no restore possible

Long-term availability
●
Technical
– Future availability of your backup software on future
hardware?
– Future availability of hardware drivers to read your media?
●
Avoid vendor lock-in
– Pay-per-use when you need a restore?
– Limited usage allowance – Examples from the field
●
No restart after license key expiration possible
●
Obligation to delete software after subscription ends
– Vendor of backup software goes out of market ?

Open Source is crucial for backups
●
Distinguish between real open source
and ‘open core’
●
No vendor-lock-in
●
Even if companies backing a project disappear:
code is still available and can be adapted
●
Future-proof and adaptable to future hardware:
only with open source
●
Let’s you reclaim your data, if you backup to cloud

Requirements summary
●
Backup software only future-proof,
if 100% open source
●
Be prepared against ransomware and the
unexpected:
– Keep extra copies of your encryption keys
– Separate backup data
– Use backup replication, different media (worm)
– Backup data easy accessible to enable fast
recovery in minimal environment
