Hi, Thank you for response.
I did restart for all the nodes and now I can see files in backup folders so It seems like it is working. During this process I have noticed to something very strange In data/City folder there are files that are not created in the snapshot folder (it looks like old orphaned files) Is there any process of cassandta that will delete uneeded files I tried to run nodetool cleanup but it did not help. This is the files: -rw-r--r-- 1 cassandra cassandra 230281 2011-12-06 00:57 AttractionCheckins.3039706172746974696f6e-f-157-Data.db -rw-r--r-- 1 cassandra cassandra 1936 2011-12-06 00:57 AttractionCheckins.3039706172746974696f6e-f-157-Filter.db -rw-r--r-- 1 cassandra cassandra 27 2011-12-06 00:57 AttractionCheckins.3039706172746974696f6e-f-157-Index.db -rw-r--r-- 1 cassandra cassandra 4264 2011-12-06 00:57 AttractionCheckins.3039706172746974696f6e-f-157-Statistics.db -rw-r--r-- 1 cassandra cassandra 1321 2011-12-06 00:58 AttractionCheckins.3039706172746974696f6e-f-158-Data.db -rw-r--r-- 1 cassandra cassandra 16 2011-12-06 00:58 AttractionCheckins.3039706172746974696f6e-f-158-Filter.db -rw-r--r-- 1 cassandra cassandra 27 2011-12-06 00:58 AttractionCheckins.3039706172746974696f6e-f-158-Index.db -rw-r--r-- 1 cassandra cassandra 4264 2011-12-06 00:58 AttractionCheckins.3039706172746974696f6e-f-158-Statistics.db -rw-r--r-- 1 cassandra cassandra 2627100 2011-12-06 06:55 Attractions.3039706172746974696f6e-f-1156-Data.db -rw-r--r-- 1 cassandra cassandra 1936 2011-12-06 06:55 Attractions.3039706172746974696f6e-f-1156-Filter.db -rw-r--r-- 1 cassandra cassandra 20 2011-12-06 06:55 Attractions.3039706172746974696f6e-f-1156-Index.db -rw-r--r-- 1 cassandra cassandra 4264 2011-12-06 06:55 Attractions.3039706172746974696f6e-f-1156-Statistics.db -rw-r--r-- 1 cassandra cassandra 2238358 2011-12-06 07:50 Attractions.3039706172746974696f6e-f-1157-Data.db -rw-r--r-- 1 cassandra cassandra 16 2011-12-06 07:50 Attractions.3039706172746974696f6e-f-1157-Filter.db -rw-r--r-- 1 cassandra cassandra 20 2011-12-06 07:50 Attractions.3039706172746974696f6e-f-1157-Index.db -rw-r--r-- 1 cassandra cassandra 4264 2011-12-06 07:50 Attractions.3039706172746974696f6e-f-1157-Statistics.db -rw-r--r-- 1 cassandra cassandra 92 2011-12-06 07:50 Attractions.3039706172746974696f6e-f-1158-Data.db -rw-r--r-- 1 cassandra cassandra 16 2011-12-06 07:50 Attractions.3039706172746974696f6e-f-1158-Filter.db -rw-r--r-- 1 cassandra cassandra 20 2011-12-06 07:50 Attractions.3039706172746974696f6e-f-1158-Index.db -rw-r--r-- 1 cassandra cassandra 4264 2011-12-06 07:50 Attractions.3039706172746974696f6e-f-1158-Statistics.db -rw-r--r-- 1 cassandra cassandra 44799 2011-12-06 01:25 CityResources.3039706172746974696f6e-f-365-Data.db -rw-r--r-- 1 cassandra cassandra 1936 2011-12-06 01:25 CityResources.3039706172746974696f6e-f-365-Filter.db -rw-r--r-- 1 cassandra cassandra 196 2011-12-06 01:25 CityResources.3039706172746974696f6e-f-365-Index.db -rw-r--r-- 1 cassandra cassandra 4264 2011-12-06 01:25 CityResources.3039706172746974696f6e-f-365-Statistics.db -rw-r--r-- 1 cassandra cassandra 7647 2011-12-06 07:50 CityResources.3039706172746974696f6e-f-366-Data.db -rw-r--r-- 1 cassandra cassandra 24 2011-12-06 07:50 CityResources.3039706172746974696f6e-f-366-Filter.db -rw-r--r-- 1 cassandra cassandra 96 2011-12-06 07:50 CityResources.3039706172746974696f6e-f-366-Index.db -rw-r--r-- 1 cassandra cassandra 4264 2011-12-06 07:50 CityResources.3039706172746974696f6e-f-366-Statistics.db Thanks Michael From: Alain RODRIGUEZ [mailto:arodr...@gmail.com] Sent: Wednesday, January 18, 2012 10:40 AM To: user@cassandra.apache.org Subject: Re: Incremental backups As this option is in the cassandra.yaml file, you might need to perform a restart of your entire cluster (a rolling restart should work). Hope this will help. Alain 2012/1/18 Michael Vaknine <micha...@citypath.com> Hi, I am configured to do incremental backups on all my node on the cluster but it is not working. In cassandra.yaml : incremental_backups: true When I check data folder there are some keyspaces that has folder backups but empty and I suspect this is a folder created in the past when I had 0.7.6 version. In a new creted Keyspace the folder does not exists. Does someone know if I need to configure any thing besides cassandra.yaml for this to work? Thanks Michael
