Before contemplating archiving solutions for your group, please check whether your group already possesses a ZDV-archive. If in doubt, please write a mail to
email@example.com with your inquiry.
Likewise you can apply for an archive at
firstname.lastname@example.org. Please note, that external users will be send an invoice on a yearly basis. Please ask for conditions in your mail. Internal users should be aware that there is currently no charge to them.
Instead of specifying the archive server always as
tsm02.zdv.uni-mainz.de, use the one assigned for your group. This will be
tsm02 for most practical purposes, we therefore used that for our examples.
The archiving software is wrapped with a script. In order to list filespaces which have been archived invoke it like
$ /cluster/bin/tsmarchive tsm02.zdv.uni-mainz.de archivetest query filespace
Output will be like:
> IBM Tivoli Storage Manager > Command Line Backup-Archive Client Interface > Client Version 7, Release 1, Level 6.5 > Client date/time: 08/18/2017 12:23:03 > (c) Copyright by IBM Corporation and other(s) 1990, 2017. All Rights Reserved. > > Node Name: ARCHIVETEST > Please enter your user id <ARCHIVETEST>:
Now, users need to confirm with their ID, which is identical to the node in question (this is information you obtain with your archiving account), and hitting
Then, your password is required:
> Please enter password for user id "ARCHIVETEST":
An alternative way is to provide the password with
-password on the command line.
It is possible to inquire what has been archived, e.g. on
$ /cluster/bin/tsmarchive tsm02.zdv.uni-mainz.de archivetest query archive /gpfs/fs1/ -subdir=yes -password=<your password>
When knowing a given description, one can search for it:
$ /cluster/bin/tsmarchive tsm02.zdv.uni-mainz.de archivetest query archive c:\ -su=y -descr="some description"
Before contemplating to archive data, please separate data from other files (e.g. testing scripts which will fulfill no purpose in re-creating results or intermediate results, which do not merit archiving). Consider which files need archiving (results? or experimental raw data?). But most importantly: Limit the number of files to be archived by creating (compressed) tar balls or zipped directories. The reason is: Archiving hundreds of thousands of files is not a good idea - because of the technical overhead and the resulting loss in overview, too.
The following command would archive the
bin/ directory. The associated description would merely be the time stamp:
$ /cluster/bin/tsmarchive tsm02.zdv.uni-mainz.de <archivename> archive bin/
A more meaningful description can be supplied on the command line, too:
$ /cluster/bin/tsmarchive tsm02.zdv.uni-mainz.de archivetest archive <directory or file to be archived> -subdir=yes -description=\"My super important sampling scripts for DESY beamline\"
In order to archive directories recursively you need to specify the
-subdir=yes flag and a trainling slash (
/) has to be amended to the directory to be archived.
To be useful descriptions should fulfill the following criteria to support preservation and re-use (as a rule of thumb):
Try to be as concise as possible. Descriptions should be stored separately (e. g. a classic folder in your institute) tabulating stored data, dates and the description.
When invoking the archiving command the client might complain about existing files it cannot write to (particularly
dsminstr.log1). Try to delete those and proceed.
$ /cluster/bin/tsmarchive tsm01.zdv.uni-mainz.de archivetest retrieve <path you want to restore> -sub=yes -descr=\"<your description>\"
The description can be omitted, but in case of double entries (entries with identical paths but different descriptions) a description is mandatory to retrieve the correct archive version.
If a recursive retrieval for a given path is desired a trailing slash
/ is required to amend to your path, like when archiving.
Getting help is as simple as:
$ /cluster/bin/tsmarchive tsm01.zdv.uni-mainz.de archivetest help
$ /cluster/bin/tsmarchive tsm01.zdv.uni-mainz.de archivetest help archive
