kandi X-RAY | zfsbackup-go Summary

zfsbackup-go is a Go library typically used in Backup Recovery, Continuous Backup applications. zfsbackup-go has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

This backup software was designed for the secure, long-term storage of ZFS snapshots on remote storage. Backup jobs are resilient to network failures and can be stopped/resumed. It works by splitting the ZFS send stream (the format for which is committed and can be received on future versions of ZFS as per the man page) into chunks and then optionally compresses, encrypts, and signs each chunk before uploading it to your remote storage location(s) of choice. Backup chunks are validated using SHA256 and CRC32C checksums (along with the many integrity checks builtin to compression algorithms, SSL/TLS transportation protocols, and the ZFS stream format itself). The software is completely self-contained and has no external dependencies. This project was inspired by the duplicity project.

How to disable azure cosmos db continious backup

Asked 2022-Feb-22 at 10:59

I enabled the Azure cosmos DB continuous backup for one of my Cosmos DBs.
How can I disable it? It just says you have successfully enrolled in continuous backup.

I am not sure if you have seen this message in the portal when you created the account/also mentioned in the doc

"You will not be able to switch between the backup policies after the account has been created"

since you need to select either "Periodic" or "Continuous" at the creation of Cosmos Account, it becomes mandatory.

Update:

You will not see the above in portal anymore, you can Switch from "Periodic" to "Continous" on an existing account and that cannot be reverted. You can read more here.

QUESTION

Consistency of Continuous backup of Azure Cosmos DB

Asked 2021-Nov-25 at 17:15

What would be the consistency of the continuous backup of the write region if the database is using bounded staleness consistency? Will it be equivalent to strong consistent data assuming no failovers happened?

Thanks Guru

ANSWER

Answered 2021-Nov-25 at 17:15

Backups made from any secondary region will have data consistency defined by the guarantees provided by the consistency level chosen. In the case of strong consistency, all secondary region backups will have completely consistent data.

Bounded staleness will have data that may have stale or inconsistent data inside the defined staleness window (minimum 300 seconds or 100k writes). Outside of that staleness window the data will be consistent.

Data for the weaker consistency levels will have no guarantees for consistency from backups in secondary regions.

QUESTION

Mongo atlas recommends cloud provider snaphots for backup - Is it effective?

Asked 2020-May-19 at 10:12

MongoDB has deprecated the continuous back up of data. It has recommended using CPS (Cloud provider snapshots). As far as I understood, snapshots isn't really going to be effective compared to continuous backup coz, if system breaks, then we can only be able to restore the data till the previous snapshot which isn't gonna make the database up-to-date or close to it atleast.

Am I missing something here in my understanding?

Cloud provider snapshots can be combined with point in time restore to give the recovery point objective you require. With oplog based restores you can get granularity of one second.
