kandi X-RAY | SpectrumScaleAutomation Summary
IBM Spectrum Scale is a software-defined scalable parallel file system storage providing a comprehensive set of storage services. Some of the differentiating storage services are the integrated backup function and storage tiering. These services typically run in the background according to pre-defined schedules. This project presents a flexible framework for automating storage services in IBM Spectrum Scale or other software.

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 SpectrumScaleAutomation
all manager and / or quorum nodes OR Spectrum Archive EE nodes. The launcher and the required storage service components have to be installed on these nodes.
all nodes that are in the predefined node class to run the storage service. Only the required storage service components have to be installed on these nodes.
identify the nodes where the components have to installed, see guidance above
on each node create a directory referenced by the parameter scriptPath
copy the required components (files) to the respective nodes into the appropriate directory
install the custom events file (more information below).
adjust parameters in the launcher, backup and migrate script (more information below)
test the launcher and the operations. Note that launcher does not write output the the console (STDOUT) but into a log file located in /var/log/automation
schedule the launcher using a scheduler, e.g. cron
