The Question is: Dear Wizard, I have a old Tape (from VMS 4.7) with one urgent Backup-Saveset on it. After a FTP-Copy from the saveset (the tape was read by an IBM host and then transferred over ftp to an PC and from the PC over ftp to the VAX) and changing the file-attributes the sav eset is not accessable. When I try a BACKUP/LIST the following error message appears: $ backup/list KKNR1DAT.DAT;1/save Listing of save set(s) %BACKUP-E-INVRECSIZ, invalid record size in save set %BACKUP-E-INVRECTYP, invalid record type in save set %BACKUP-E-INVRECSIZ, invalid record size in save set %BACKUP-E-INVRECSIZ, invalid record size in save set %BACKUP-E-INVRECTYP, invalid record type in save set %BACKUP-E-INVRECSIZ, invalid record size in save set %BACKUP-E-READERRS, excessive error rate reading SYS$SYSROOT:[SYSMGR]KKNR1DAT.DA T;1 -BACKUP-E-HDRCRC, software header CRC error %BACKUP-I-OPERSPEC The reset with the procedure: RESET_BACKUP_SAVESET_ATTRIBUTES.COM creates an "error" when reading the file! What can I do? this is the only version of the file Thanks Harald Pusch The Answer is : You may well have a media-level problem or error, but first please try to eliminate the intermediary systems and network transfers -- try accessing the particular BACKUP tape media involved directly from an OpenVMS system. Additionally, network transfers are known as occasional sources of OpenVMS file attribute corruptions. A tool to correct the most common BACKUP saveset file attribute corruptions is available via the OpenVMS FAQ. Failing that, you will want to contact a data recovery service -- such a service may or may not be able to recover the data from the particular tape media involved here. Topics specific to unintential initialization or the overwriting of disk and tape media include (1286) and (6990). For errors resulting from file structure, directory structure, or file structure corruptions, please see topics such as (1213), (4088), (4571), (5071), (5553), (5719), (6021), (6234). If you want to overwrite the data on the media, related topics include (841), (3926), (4286), (4598), and (7320).
