NAME

gammu-smsbackup - gammu(1) SMS backup file format.

The SMS backup format is text file encoded in current encoding of platform where Gammu is running.

This file use ini file syntax, see ini.

SECTIONS

The file consists of sections, whose name starts with SMSBackup. When creating the backup file, three digits are appended to this text defining order. While reading the backup, any part after SMSBackup text is ignored and everything which begins with this is processed. So you can as well give the section name SMSBackupFoo and it will be processed.

The number of messages in backup file is currently limited by GSM_BACKUP_MAX_SMS (100000 at time of writing this document).

SMSBackup section

Each section interprets one physical SMS message (eg. one message part in case of multipart messages).

Decoded text

For SMS backups created by Gammu, there is a decoded text as a comment just after the section name:

[SMSBackup001]
; This is message text

The text can be split to more lines if it is too long or of original message included new lines.

NOTE:

This is easiest way to get message text, however also the least reliable one, because it is stored in the comments in the file.
