ntbackup - compress

[GK]

Hello,

I am using ntbackup in XP for backing up 2 folders on daily basis. Destination is a server where I have been allocated a limited space. Sine the backup file size is increasing regularly, I want to compress (similar to WinZip) these folder contents during backup. Is it possible in ntbackup ?

Regards,
GK

No, it is not. The "compress" switch in ntbackup is a signal that tells the backup device, usually a tape drive, to turn on hardware compression.

NTbackup is a stripped-down Veritas "Backup Exec,"
and doesn't offer software compression for disk file output
(it even seems to be able to read uncompressed Backup Exec backups,
and vice-versa, except for "system state" components).

However, if you only want to back up two folders (not "system folders"),
why not use WinZip itself (with command-line interface) directly,
or 7-Zip, etc.?

The original standardized "Zip" archive format can handle up to 65535 files,
and the extended format (WinZip version 9 or later) is virtually unlimited.

WinZip is not equipped, however, to "shadow" files in use during backup,
which NTbackup seems to be (equivalent to Veritas "Open Files Option"?)

Alternatively, perhaps WinZip can compress the NTbackup output files,
after backups are completed?
