I don't see any mention of support for SiS (single-instance-storage) as discussed previously on the list, even for upcoming 1.2/2.0 Did this fall through a crack? Or did you decide it was going to be too difficult for the time being?
dbox-file.h contains: /* Pointer to external message data. Format is: 1*(<start offset> <byte count> <ref>) */ DBOX_METADATA_EXT_REF = 'P', That's about all there exists of that feature :) I haven't given up on implementing that, but for now there have been more important things.
Fair enough... but since this one is near and dear to my heart ;)
Do you have any idea as to a time frame for when you might be able to get to it? Are you thinking post v2.0? Even 2.1 or 3.0?
I know its a hard question to answer, so if you just have no idea, thats ok too...
Thanks again -
Another option to consider is server side deduplication such as the ASIS block-level deduplication offered by NetApp (requires nearstore license). Our site will be migrating to a new netapp cluster that supports dedupe and I will probably use it for mail. Although I doubt it does anything for tape backups, I assume those will be full size. Dovecot is cheaper too :)
