OVH Cold Storage

[anayrat]

Hello,
It is not an issue, I just wanted to share my experience with OVH Cold Archive (different from Cloud Archive).

I created two buckets, on hot (metadata) and another cold (data):

Here is my ovh-cold.toml configuration:

[global]
#log-level = "debug"

[repository]
repository = "opendal:s3"
repo-hot = "opendal:s3"
password = "xxxxxx"
warm-up-command  = "s3cmd restore --restore-days=3 -dv s3://nas-cold/nas-cold/%path"

[repository.options]
endpoint = "https://s3.eu-west-par.io.cloud.ovh.net"
region = "eu-west-par"
access_key_id = "xxxxx"
secret_access_key = "xxxx"

# options only for hot part
[repository.options-hot]
bucket = "nas-hot"
root = "/nas-hot"

# options only cold part
[repository.options-cold]
bucket = "nas-cold"
root = "/nas-cold"
default_storage_class = "DEEP_ARCHIVE"

Notice the warm-up-command, I had to create an s3cmd config for my ovh bucket.

Here is the command I use to backup:

rustic  backup   -P ovh-cold --set-compression 12  /folder

If I want to restore:

rustic  restore   -P ovh-cold latest:"myfile"  /destination/

rustic will send warm up command for each chunk. I did not investigate how to send batch command.

Due to cold archive limitation, warmup take more than 48 hours. The first restore will fail and after 48H, you will be able to restore file.
