Script needed to copy a single file to USB drive but only keep the last 3 versions

Hello, I have been using the above code at each of my schools and it has been working great. I have just taken over a new school where the backup data is much larger so I can only fit 1 backup on the USB drive each night and not the 3 that the code currently does.

 

What do I need to change in the code so it only copies 1 backup file to the USB and then deletes this the next night before copying the next backup.

 

BTW if I had to guess its something to do with the -Skip 2 section.

 

Thanks for your time, again

At a very quick glance you need to change the Select-Object -Skip 2 - If you are only wanting the latest I don't think you even need to do the skip. But if you play around trying that on 1 or removing that section you should get sorted.

Can try this.

 

Obviously in a test environment first.

Can try this.

I have fixed the formatting...

 

#Requires -Version 3.0
$Source = "C:\iSCSIVirtualDisks\man-vd.vhdx"
$Destination = "E:"
$TargetDir = "{0}{1}" -f $Destination, (Get-Date).ToString("yyyy-MM-dd HH.mm.ss")

Get-ChildItem -Path $Destination -Directory | Where-Object { $_.Name -match "^\d{4}-\d{2}-\d{2} \d{2}\.\d{2}\.\d{2}$"} | Sort-Object LastWriteTime -Descending | Remove-Item -Force -Recurse

If (-not(Test-Path "$TargetDir")) { 
 $Null = New-Item "$TargetDir" -Type Directory; 
 Copy-Item -Path "$Source" -Destination "$TargetDir" -ErrorAction Stop -Verbose 
}

Thank you, sorry about bad formatting, I replied on my phone.

[TwistedHelixis]

Thanks, Will let the script run later and see how it does.

Let us know how you get on!

[TwistedHelixis]

All working fine, thanks :0)

Hi all :0)

 

Currently the source is set to $Source = "C:\iSCSIVirtualDisks\man-vd.vhdx"

 

If I wanted to backup the iSCSIVirtualDisks folder rather than the single file in the folder, am I OK simply deleting the \man-vd.vhdx section?

 

Basically I have a few other files in that folder now that I need copying to the USB drive.

With a quick glance at it yes should be fine.

[TwistedHelixis]

Just ran the script and it does not work with just C:\iSCSIVirtualDisks

 

The script deletes the older folders, creates the dated folder with the iSCSIVirtualDisks folder inside but the files are not copied.

[QwertyMash]

Did you put a \ at the end of the source or not? Can you give us the latest version of the script? (I am at work so having to be sly haha)

[TwistedHelixis]

I am at work so having to be sly haha

I can wait until later if needed :0)

 

tried with and without the \

 

#Requires -Version 3.0

$Source = "C:\iSCSIVirtualDisks"

$Destination = "E:"

 

$TargetDir = "{0}{1}" -f $Destination, ((Get-ItemProperty $Source).LastWriteTime).ToString("yyyy-MM-dd HH.mm.ss")

 

Get-ChildItem -Path $Destination -Directory | Where-Object { $_.Name -match "^\d{4}-\d{2}-\d{2} \d{2}\.\d{2}\.\d{2}$"} | Sort-Object LastWriteTime -Descending | Select-Object -Skip 2 | Remove-Item -Force -RecurseIf (-not(Test-Path "$TargetDir")) { $Null = New-Item "$TargetDir" -Type Directory; Copy-Item -Path "$Source" -Destination "$TargetDir" -ErrorAction Stop -Verbose }

So you want to copy the C:\iSCSIVirtualDisks folder?

and only copy so many copies of it in the destination folder?

 

I've forgotten what the end goal was haha.

[TwistedHelixis]

So you want to copy the C:\iSCSIVirtualDisks folder?

Yes, I can only fit a few copies of this folder on a USB drive. I will also be using more than one USB drive which will get switched each week.

[TwistedHelixis]

Hold on, my original script is now not working, perhaps something else is going on. Hold on and I will get back

[QwertyMash]

USB drives for back ups? I'd consider something a little less volatile myself like haha.

I finish work at 4, I will look at this tonight for you if no one replies earlier with the solution for you.

I feel like what I said earlier as a modification should have worked at a quick glance at it so yes maybe something else is wrong

[TwistedHelixis]

OK rebooted the server and my original file works but not the one with just the folder name

[TwistedHelixis]

USB drives for back ups?

 

90% of all our files are cloud based, with cloud 2 cloud Spanning backup. For the few bits onsite that need backing up (DC etc) I have an onsite iSCSI server. I then wanted a way to have a few backups either offsite or in the safe which is where the USB drives come in.

[QwertyMash]

Glad you got the original working. As I say, if no one manages to help you before I get home, I will look at the script tonight when I am not at work and make the adjustments you need.

[TwistedHelixis]

I know my script powers are not strong but would the issue be to do with the -RecurseIf in the script?

 

EDIT - ignore me its not that.

Hi, I have been trying and failing to write my own script. I have setup a test folder on my laptop and have used the script below as a start but I still end up copying just the iSCSIVirtualDisks folder and not both the files in the folder. I also found a completely different script online but that did not even run.

 

For anyone that has jumped to this last thread - I now need to copy a folder or the contents of a folder (2 large files) from the C drive to an external USB drive. The folder to be copied contain 2 very large files and the external USB will only be able to store the last 2 copies, so I need a way to to backup the files in to a folder with the current date / time and also need a way to delete older backups from the USB. The script below works perfectly when copying just 1 file to the USB but I now have more then one file in the iSCSIVirtualDisks folder to get copied :0)

 

Sorry, I know I am a pain in the bum but would be very grateful for some help.

 

#Requires -Version 3.0

$Source = "C:\iSCSIVirtualDisks\man-vd.vhdx"

$Destination = "E:"

 

$TargetDir = "{0}{1}" -f $Destination, ((Get-ItemProperty $Source).LastWriteTime).ToString("yyyy-MM-dd HH.mm.ss")

 

Get-ChildItem -Path $Destination -Directory | Where-Object { $_.Name -match "^\d{4}-\d{2}-\d{2} \d{2}\.\d{2}\.\d{2}$"} | Sort-Object LastWriteTime -Descending | Select-Object -Skip 2 | Remove-Item -Force -RecurseIf (-not(Test-Path "$TargetDir")) { $Null = New-Item "$TargetDir" -Type Directory; Copy-Item -Path "$Source" -Destination "$TargetDir" -ErrorAction Stop -Verbose }

OK so the script below does copy the folder with both files but it deletes the older files based on the amount of days the files have been in the destination. What I need is to always keep the last couple of backups no mater the date, similar to the script above that works with one file.

 

Write-Host("Copying logs to place")

if (Test-Path("C:\iscsi")){

Get-ChildItem -Path "D:\folder" | Where-Object {$_.psiscontainer -and $_.lastwritetime -le (get-date).adddays(-7)} | ForEach {remove-item $_.fullname -Force -Recurse -ErrorAction SilentlyContinue } # Clears out files older than 7 days

 

Get-Childitem -Path "C:\iscsi" | Copy-item -Destination "D:\folder" -Force

}

else{Write-Host("*** Error: logs not copied")}

 

 

EDIT - It also does not create a new folder or filename for each backup, I think it is just overwriting the old backup which is no good.
