Translate to:

Symptoms

Backup to Acronis Storage / Acronis Storage Gateway fails with error:

sslv3 alert certificate expired

Storage certificate is issued for a specific period of time and is automatically updated before it expires. It is stored locally on the Acronis Storage / Acronis Storage Gateway and Backup Agents.

To check certificate validity date:

  1. Run the following command:

on a FES node of Acronis Storage:

# openssl x509 -in /mnt/fes/data/ca-certs/reg.crt -text

on Acronis Storage Gateway:

# openssl crl -in /etc/pki/tls/certs/Acronis/storage/reg.crl -noout -text

and

# openssl x509 -in /etc/pki/tls/certs/Acronis/storage/reg.crt -text

  2. Check the validity or update dates:

 Validity
            Not Before: Aug 12 12:55:12 2015 GMT
            Not After : Aug 11 12:55:12 2016 GMT

 Update
            Last Update: Aug 12 12:55:12 2015 GMT
            Next Update: Aug 11 12:55:12 2016 GMT

  3. If current date is not in this period, the certificate has expired.

Cause

Acronis Storage
Typical root cause is a connectivity problem when Acronis Backup Cloud servers are unreachable from Acronis Storage / Acronis Storage Gateway. As a result the certificate is not updated automatically.

Acronis Storage Gateway
Issue is known. Wrong permissions are set to folder /etc/pki/tls/certs/Acronis/storage during Acronis Storage Gateway registration and result into automatic certificate update failure.

Solution

See Acronis Backup Cloud: how to re-register Service Provider hosted storage.
