We have sharepoint on-premises servers 2013/2016 , which have the following architecture:-
windows server 2012/2008 R2 which act as the application servers.
windows server 2012/2008 R2 which act as the database servers.
Now our IT admins, take snapshots of the servers (application + database) on daily basis + to have additional restore point (in case we faced a sever damage to our servers) i run this command on daily basis to have a backup for the whole farm :-
Backup-SPFarm -Directory \*****\backups\ -BackupMethod full -BackupThreads 10 -Force
but my questions are, if our approach is sufficient to covers these scenarios:-
let say the database server had a major hardware/OS problem, and we are not able to have it working again. then will the snapshot we have for the database be able to recover us from the database server failure?
similar to point one, but let say the application server had a major hardware/OS problem? will the snapshot be sufficient to recover us from the application server failure?
since our IT admin are taking snap shots of the servers, then is there any need to do a Backup-SPFarm? as this command will created a huge backup files.
Thanks in advance for any help.
