◆ numberedBackupFile()

KCOREADDONS_EXPORT bool KBackup::numberedBackupFile ( const QString & filename,
const QString & backupDir = QString(),
const QString & backupExtension = QStringLiteral("~"),
const uint maxBackups = 10 )

Function to create a backup file for a given filename.

This function creates a series of numbered backup files from the given filename.

The backup file names will be of the form: <name>.<number><extension> for instance

chat.3.log 

The new backup file will be have the backup number 1. Each existing backup file will have its number incremented by 1. Any backup files with numbers greater than the maximum number permitted (maxBackups) will be removed. You can use this method even if you don't use KSaveFile.

Parameters
filenamethe file to backup
backupDiroptional directory where to save the backup file in. If empty (the default), the backup will be in the same directory as filename.
backupExtensionthe extension to append to filename, which is "~" by default. Do not use an extension containing digits.
maxBackupsthe maximum number of backup files permitted. For best performance a small number (10) is recommended.
Returns
true if successful, or false if an error has occurred.
