kandi X-RAY | Zimbra live sync scripts Summary

Zimbra live sync scripts is a Shell library typically used in Backup Recovery, Continuous Backup applications. Zimbra live sync scripts has no bugs, it has no vulnerabilities, it has a Strong Copyleft License and it has low support. You can download it from GitLab.

This is an experimental solution to providing near-live synchronisation between two Zimbra servers so that one of them is live and the other is kept in a warm or very warm standby state. The system is symmetrical. The sync can work in reverse when the mirror server becomes the active server. This allows easy fall-back to the original server once the failover condition is resolved. Zimbra employs several different databases to store messages, message indexes, meta-data, account information and configuration. Although it is possible to synchronise two Zimbra servers at the disk level using DRBD or VSphere, the amount of disk operations from all these databases that need to be replicated would probably take up a lot of bandwidth which may be debilitating and/or expensive to implement if the two servers are in remote locations. Fortunately, Zimbra keeps a log of almost all it's transactions in the redolog. The only thing not logged here are changes to the LDAP database. An incremental backup is made up of an LDAP dump and a collection of redologs. An incremental backup can be used to bring a backup server up to date if the if the last full backup of the backup server was more recent than the oldest log in the redolog.

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.
