Compression types

Post by paulkaye »

Hi,
Firstly, congratulations on reaching the milestone of releasing Reflector!
This is not my only backup mechanism, and my intention for this particular backup is to generate a single encoded ZIP file containing all of the files within a particular directory structure. My question is about the "compression type" options under the "archive" tab. The dropdown menu provides the options of: (i) compress files individually, (ii) separated monolithic archives, and (iii) global monolithic archive.
1) Which of these options is appropriate for what I'm trying to achieve?
2) What is the difference between separated and global? e.g. What is separated and on what basis?
3) What file type is the archive?
4) The latter two are labeled "not recommended" - can you explain why?

Thanks,
Paul

Thanks

1- Global monolithic archive is the one
2- Separated creates an archive for each source. Global just creates an archive with all sources
3- Zip files
3- You cannot use incremental backups with those. Also if the archive gets corrupted for some reason, all the files are gone. Not the case with individual file compression (or no compression) when a corrupted archive affects just one file.

Can you use Differential backup to SFTP target with either single or global monolitic archive? See its a bit unhandy to upload dozens of small files due to connection overhead for each file.

Yes, compression can be used with ftp/sftp.

OK, but does this also work with monolitic archives? When selected it says "Monolitic can use local resources only". No idea what that means.
thx

It works with ftp as the destination, but not as the source.
