Question Best backup system local before upgrade

[VirtualCed]

Hello,

I have a Plesk Onyx 17.07 running on a server with 3 SSD.
Right now, disk1 is the server os and data
disk 2 is only used for local backups
disk 3 is not used.

I plan to migrate to 17.5.3 version as proposed by the system.

I'd like to have the most reliable backup.

So I thought it could be a good idea to clone SSD1 to SSD3.
In case of trouble I should be able to restore it from SSD3 to SSD1.

I'd like to have your opinion :

Is is safe enough ?
which tool should I use ?
At this time I'm thinking to

• dd
• rsync
• partclone

Any advice ?

Thanks

It should be noted that the upgrade procedure is very easy. There should not be any problems.
But if you want to make a dump of the server, just in case, I would advise it to be done quickly using dd.
