Running time driven backup script but just once - google-apps-script

Question

I have an archiving script which is now working as it should (I have included it below). However I would like it to run only at 1 am on the date the sheet is in use for.I make the sheets and name them months in advance and they sit in drive until the day of use (maybe earlier if we get pre bookings) but i don't want them to run the script and archive every night at 2 AM! Is there any way to make the time driven trigger only once? At moment the time driven trigger doesn't copy over when i copy the blank sheet either. Any ideas or a better way of automating this? Thanks.
function dataBackup() {
var inputSS = SpreadsheetApp.getActiveSpreadsheet();
var archiveSS =
SpreadsheetApp.openById('146WU8RghfFqlCpCSX7n6kBAKOyxcpVKt14yhVfvYz-g');
var user = Session.getActiveUser().getEmail();
var sheetNames = ['AM trip', 'PM trip', 'Pool / Beach', 'Night Dive'];
for (var i = 0; i < sheetNames.length; i++) {
var inputSheet = inputSS.getSheetByName(sheetNames[i]);
var archiveSheet = archiveSS.getSheetByName(sheetNames[i]);
var date = inputSheet.getRange('A2').getValue(); // Changed to stop
inadvertent cell changes, also made text white so not seen.
var data =
inputSheet.getRange('E7:U37').getValues().filter(function(row) { return
row[0] !== '' || row[1] !== ''});
for (var x = 0; x < data.length; x++) {
data[x].splice(0, 0, date);
}
var getDate = archiveSheet.getRange(archiveSheet.getLastRow(),
1).getValue();
var maxRowLength = data.reduce(function(length, row) { return
Math.max(length, row.length); }, 0);
var date = new Date(date);
var getDate = new Date(getDate);
if (getDate.getDate() != date.getDate() || getDate.getMonth() !=
date.getMonth()) {
if (data.length != 0) {
archiveSheet.insertRowsAfter(archiveSheet.getLastRow(),
data.length);
archiveSheet.getRange(archiveSheet.getLastRow() + 1, 1,
data.length, maxRowLength).setValues(data);
} else {
archiveSheet.insertRowsAfter(archiveSheet.getLastRow(), 1);
archiveSheet.getRange(archiveSheet.getLastRow() + 1, 1, 1,
2).setValues([[date, 'No Data']]);
}
}
}
}

Set your trigger to only go off once monthly? E.g. Weekly or set date?
As for triggers copying over they won't due to the way Google have made their service. Doesn't take long to set them up.
