Just Curious: How does atlas achieve snapshot backup?

Which file systems does atlas use in order to achieve snapshot backups?

I was under the impression that btfrs is used, which has this feature, but then the responses on my post about btfrs suggest it shouldn’t be used.

Hi @Dushyant_Bangal,

Atlas uses Cloud Provider capabilities to snapshot the storage. Each cloud might have its own mechanics, however. all of them are reliable and proven to work.


Best regards,

Hi @Pavel_Duchovny, can you provide info about which filesystem is used underneath?

Hi @Dushyant_Bangal,

Each cloud provider have its own disk types (EBS, SSD, Premium storage).

They are mounted as xfs file systems according to our best practices.
