Hello All, I was using venti/write to store off small data sets which are less than a datablock in size earlier. But now I have started using vac for larger data but I have come across this problem:
Writing the same datablock to the venti server used to give me the same score always. But vac does not have that property. If I store the same file many times it gives me different scores. for eg: using venti/write --------------- ano...@anoopm-laptop:~/workspace/ServerBackEnd$ ./write -h 127.0.0.1 < msg 00ef06474fb2fe5720eb39eb86c85d96f00362e2 ano...@anoopm-laptop:~/workspace/ServerBackEnd$ ./write -h 127.0.0.1 < msg 00ef06474fb2fe5720eb39eb86c85d96f00362e2 ano...@anoopm-laptop:~/workspace/ServerBackEnd$ ./write -h 127.0.0.1 < msg 00ef06474fb2fe5720eb39eb86c85d96f00362e2 using vac ------------- ano...@anoopm-laptop:~/workspace/ServerBackEnd$ ./vac -h 127.0.0.1 msg vac:5563f21a3f4d1b783175d57b029ca7d0f210d036 ano...@anoopm-laptop:~/workspace/ServerBackEnd$ ./vac -h 127.0.0.1 msg vac:49c3411166ad14afc30d5d3b6a5ec487ce9246d7 ano...@anoopm-laptop:~/workspace/ServerBackEnd$ ./vac -h 127.0.0.1 msg vac:977e275c94de5ce6d03163ff85243e29531f961b >From vac's man page "When vac is used on a file tree that shares data with an existing archive, the consumption of storage will be approximately equal to an incremental backup" But then why does it give different scores each time? This might be an expected behaviour. But can any of you please suggest a work around for my problem? Thanks in advance. Regards, Anoop
