What are tdb files?
Answered by Jerry Carter on samba@lists.samba.org [1]
Samba uses a lightweight database called Trivial Database
(tdb). Here's the list (john, we should really document
this somewhere).
(*) information persistent across restarts (but not necessarily important to backup).
account_policy.tdb* | NT account policy settings such as pw expiration, etc... |
brlock.tdb | byte range locks |
browse.dat | browse lists |
connections.tdb | share connections (used to enforce max connections, etc...) |
gencache.tdb | generic caching db |
group_mapping.tdb* | group mapping information |
lang_en.tdb | Language encodings (i think). |
locking.tdb | share modes & oplocks |
login_cache.tdb* | bad pw attempts |
messages.tdb | Samba messaging system |
netsamlogon_cache.tdb* | cache of user net_info_3 struct from net_samlogon() request (as a domain member) |
ntdrivers.tdb* | installed printer drivers |
ntforms.tdb* | installed printer forms |
ntprinters.tdb* | installed printer information |
printing/ | directory containing tdb per print queue of cached lpq output |
registry.tdb | Windows registry skeleton (connect via regedit.exe) |
sessionid.tdb | session information (e.g. support for 'utmp = yes') |
share_info.tdb* | share acls |
unexpected.tdb | unexpected packet queue needed to support windows clients that respond on a difference port that the originating request) (i could be wrong on this one). |
winbindd_cache.tdb | winbindd's cache of user lists, etc... |
winbindd_idmap.tdb* | winbindd's local idmap db |
wins.dat* | wins database when 'wins support = yes' |
In the private subdirectory we have two more tdb files:
secrets.tdb* | Private information like workstation passwords, the ldap admin dn and trust account information |
passdb.tdb* | User account information if passdb backend = tdbsam is used |
The following tdb's should be backed up IMO:
nt*.tdb
account_policy.tdb
group_mapping.tdb
share_info.tdb
winbindd_idmap.tdb
secrets.tdb
passdb.tdb
Example
To back up printing.tdb:
root# ls . browse.dat locking.tdb ntdrivers.tdb printing.tdb .. share_info.tdb connections.tdb messages.tdb ntforms.tdb printing.tdbkp unexpected.tdb brlock.tdb gmon.out namelist.debug ntprinters.tdb sessionid.tdb root# tdbbackup -s .bak printing.tdb printing.tdb : 135 records root# ls -l printing.tdb* -rw------- 1 root root 40960 May 2 03:44 printing.tdb -rw------- 1 root root 40960 May 2 03:44 printing.tdb.bak ----
vfs objects = recycle recycle:keeptree = yes recycle:versions = yes recycle:touch = yes recycle:exclude = ?~$*,~$*,*.tmp,index*.pl,index*.htm*,*.temp,*.TMP recycle:exclude_dir= /tmp,/temp,/cache recycle:repository = .recycle/.recycle.%u recycle:noversions = *.doc,*.xls,*.ppt #hide files = /.recycle.*/.recycle/ #veto files = /.recycle.*/.recycle/
inherit permissions
Use the UNIX form of setgid to make all files and subdirectories belong to the enclosing group.
For example: the root directory for a samba share appears as:
# ls -ld /home/storage drwxrwxr-x 47 root dom_users 4096 Jan 31 08:09 /home/storage
change the directory so all files & subdirectories created will belong to 'dom_users' group:
# chmod g+s /home/storage
verify the results:
# ls -ld /home/storage drwxrwsr-x 47 root dom_users 4096 Jan 31 08:09 /home/storage
if you create a new file 'abc' as user 'foo' who has the primary group 'users' the file is created as
# ls -ld /home/storage/* drwxrwsr-x 47 foo dom_users 4096 Jan 31 08:09 /home/storage/abc
