function Remove-DbBackup{
<#
.SYNOPSIS
    Removes MSSQL and other sql Server backups from disk or ftp.
.DESCRIPTION
    Provides wide functionality to delete SQL backups from disk or ftp. Implemented functionality to block deletion of .bak files if .diff or .trn depend on them
.PARAMETER Path
    Specifies the name of the base level folder to search for backup files. The search for backup files will be recursive from this location if the Deph parameter is greater than 0.
.PARAMETER DbName
    Specify databases to be deleted
.PARAMETER KeepVersions
    Specifies the number of the most recent backups to keep.
.PARAMETER KeepVersionsDiff
    Specifies the number of most recent differential MSSQL backup copies to keep. File extension must be .diff
.PARAMETER KeepVersionsTrn
    Specifies the number of most recent MSSQL transaction log backups to keep. File extension must be .trn
.PARAMETER KeepVersionsWeekly
    Specifies the number of the most recent weekly backups to keep.
.PARAMETER DayOfWeek
    Specify the day of the week. Only backups made on the specified day will be saved. By default sunday.
.PARAMETER KeepVersionsMonthly
    Specifies the number of the most recent monthly backups to keep.
.PARAMETER DayOfMonth
    Specify the day of the month. Only backups made on the specified day will be saved. By default 28.
.PARAMETER KeepVersionsYearly
    Specifies the number of the most recent yearly backups to keep.
.PARAMETER DayOfYear
    Specify the day of the year. Only backups made on the specified day will be saved. By default 365.
.PARAMETER CheckArchiveBit
    If this switch is enabled, the filesystem Archive bit is checked before deletion. If this bit is set (which translates to "it has not been backed up to another location yet", the file won't be deleted.
    Doesn't matter for files that are on the ftp server
.PARAMETER FtpCredential
    Specify ftp credentials if the backup files are located on ftp.
 
.EXAMPLE
    Remove-DbBackup -Path 'C:\MSSQL\BACKUP' -DbName "db1","db2" -KeepVersions 7 -Deph 2
    Only the 7 most recent versions of db1 and db2 will be kept
.EXAMPLE
    Remove-DbBackup -Path 'C:\MSSQL\BACKUP' -DbName "db1","db2" -KeepVersions 7 -Deph 2 -WhatIf
    Same as example #2, but doesn't actually remove any files. The function will instead show you what would be done.
    This is useful when first experimenting with using the function.
.EXAMPLE
    Remove-DbBackup -Path 'C:\MSSQL\BACKUP' -DbName "db1","db2" -KeepVersions 7 -KeepVersionsWeekly 4 -DayOfWeek Friday,Monday
    The 7 most recent versions of db1 and db2 will be kept. The last 4 copies made on Monday and Friday will also be saved.
.EXAMPLE
    $FtpCredential=Get-Credential
    Remove-DbBackup -Path 'C:\MSSQL\BACKUP',"ftp://MSSQL/BACKUP" -KeepVersions 30 -KeepVersionsWeekly 4 -KeepVersionsMonthly 12 -KeepVersionsYearly 5 -Deph 3 -FtpCredential $FtpCredential
    After executing this command, the following will be saved:
        - 30 most recent backups
        - 4 latest weekly backups (by default day of week is sunday)
        - 12 last monthly backups (by default day of month is 28)
        - 5 last yearly backups (by default day of year is 365)
.EXAMPLE
    Remove-DbBackup -Path "\\server\share\backup" -KeepVersionsMonthly 12 -DayOfMonth 1,28 -KeepVersionsYearly 6 -DayOfYear 1,365
    After executing this command, the following will be saved:
    - 12 last monthly backups made 1 and 28 day of month
    - 6 last yearly bakups made 1 and 365 day of year
.EXAMPLE
    Remove-DbBackup -Path mega:backup\SqlBackup -Deph 2 -KeepVersions 3
    Only the 3 latest versions of the database copy on mega cloud storage will be kept. You need to download rclone to the C:\Windows\PsScript folder and configure it. https://rclone.org/
