Handling of escape chars with VBoxManage in PowerShell

[floogy]

Hello,

I got general issues on finding how to escape e.g. spaces and special chars in pathnames etc. or how to address things at all <uuid|snapname> or take <name> [--description <desc>] [--live] [--uniquename Number,Timestamp,Space,Force]

Just enclose the parameters in double quotes, problem solved. Example:

The rest of the examples you have in your post are part misunderstanding of the proper command syntax, and part wrong parameters given. I'm not going to go through each and every bad command given, just pay closer attention to the syntax of each and every command.

BTW, I changed the title of your thread from "General use of vboxmanage e.g. in powershell Context: "FindSnapshot(Bstr(a->argv[2]).raw(), pSna" to something more meaningful...

PS. Friendly advice; reduce (seriously) the number of snapshots that you have! Nothing good can come out of having 24 snapshots, if one of them breaks, you're in really big trouble, see Snapshot basics to understand the fragile status of your VM as is...

[floogy]

Ah, thank you for your reply! I didn't assume, that, if one snapshot will fail by a bit change, than everything might be lost. I was oppositional thinking that it was the other way around to make it more secure. Okay, so I'll try to reduce the snapshots by the right commands (to be find) with vbox manage (hopefully). Okay snapshots doesn't replace backups, I guess.

snapshots doesn't replace backups

Snapshots are not backups (that's a tad more accurate), especially when you realize that the snapshots record sector changes and not file changes.

I'll try to reduce the snapshots by the right commands (to be find) with vbox manage (hopefully)

You have no GUI, no VirtualBox Manager? Because that makes it a lot more tedious and error-prone, and you need to be extra careful!

Make a backup in any case!

[floogy]

What happens if I delete older Snapshots? Would they merge differentialy into the lasting Snapshots? I think they are created incremental.

[socratis]

What happens if I delete older Snapshots?

I would suggest creating a throw-away VM and start experimenting. The general idea is that if you delete "Snapshot N" the content differences end up in "Snapshot N+1", which might be the "Current State". I usually start deleting from the last snapshot, and all the changes are merged into the "Current State (changed)".

Mind you, the bigger the snapshot, the more time it's going to take for the merge operation. It's not an instantaneous procedure, it might look like it's stuck but it's not, let it finish. And manage to have plenty of free space on the host, I'd say 2*Maximum_VDI_size...
