kandi X-RAY | backwrap Summary
A simple wrapper for creating backups written in bash. It currently supports borg and restic as backup tools. Compared to the well-known borgmatic, this wrapper follows another philosophy. It aims to have no dependencies other than bash and some utilities that are most likely to be present on every GNU/Linux system. In addition to handling regular files and directories, backwrap can automatically snapshot btrfs subvolumes before backing them up, which is a must when consistency matters (e.g. for database backups). It's configuration is very simple and should be doable in under 5 minutes. Also, backwrap integrates nicely with crontab and provides a built-in command for generating a suitable crontab entry with no effort. You specify the desired backup interval, and backwrap does the rest for you.

QUESTION
ANSWER
Answered 2022-Feb-22 at 10:59I 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
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 17:15Backups 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
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?
...ANSWER
Answered 2020-May-19 at 10:12Cloud 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.

Install backwrap
Clone the repository. git clone https://github.com/efficiosoft/backwrap
Adapt the sample configuration to your needs. cd backwrap cp backup.cfg.sample backup.cfg # Make your changes as documented in the sample configuration. vim backup.cfg
Run backwrap. # This will show the usage options. ./backwrap # If you haven't done already, generate a secure passphrase and # initialize the borg/restic repository to store your backups. umask 077 pwgen -s 40 1 > backup.cfg.passphrase ./backwrap init # And this will take a backup. ./backwrap backup
Optionally, set up a cronjob to take backups regularly. mkdir /etc/backwrap.d mv backup.cfg backup.cfg.passphrase /etc/backwrap.d CONFIG=/etc/backwrap.d ./backwrap gen-crontab > /etc/cron.d/backwrap
Simply pull upgrades from the master branch.
