Retention policy as recover point - issue

[fga_fer]

Hello world have a nice day.

Recently I'm facing an issue, I created a backup job to backup a VMware machine, I have created one backup repository on a compatible S3 bucket (not as SOBR), and in this job I have selected the -Retention Policy "8" restore points-.

The problem is this one:
Some backup chain does not have the Full Backup any more, I mean does not exist.
But on other backup chain the Full backup exist.

On both cases when I try to recover one incremental backup the process ends and send the follow error:

Code: Select all

Some one of you do you know

1) How this policy works mainly on a S3 compatible bucket as backup repository?
2) Is there any special configuration that we should do to prevent that the backup chain be deleted?
3) Why this could happening?
4) any idea about the root cause.

Thanks in advance to all of you.

open a Veeam support case. and please do not post logs.

what exactly is this S3 compatible system and how did you configure it?

Hi FGA

Please do not upload logs to our forum. Additionally, Every forum topic about a technical issue must provide a support case number or the topic may be deleted.

Missing/corrupted objects could been caused by lifecycle policies on the object storage side. These policies are not supported and will lead to backup and restore issues.

Therefore please open a case, and provide us with your case number.

Best,
Fabian
