The big difference I can see is the perpetual full. Bacula will upgrade a backup level to Full if no other Full is found for the client. TSM will backup any files you tell it to regardless of backup level, and TSM will keep the file for a certain amount of time (30 days, etc) after the file is deleted from the client. TSM also knows what the most current files for a client are, so like 'restore' in bacula you can choose which files to load back to the client. You do not have to select a file by job id. You can ask for a list of 'active' and 'inactive' versions of a given file or wild card and like bacula's 'restore' you can choose which files to load back. The biggest difference for what I'm wanting between bacula and TSM is the 'perpetual full'. Just backup the files from the client and let me choose which files by date to restore (bacula does the latter). I greatly agreed with the idea of Full/Differential/Incremental backups (levels 0/1/2 from BSD) until I started with TSM. The TSM method, once you understand what it is doing, works very well. I was very skeptical at first of TSM until I had used it a while. The idea is similar to CVS or RCS. Only the files that have been modified get new version numbers. Does that make sense or am I rambling? Mike ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
