23 The B<backup adddump> command creates one or more dump levels in the dump
24 hierarchy stored in the Backup Database, and optionally assigns an
25 expiration date to each one. All of the dump levels in the Backup Database
26 collectively constitute the dump hierarchy.
28 Use the B<-expires> argument to associate an expiration date with each
29 dump level. When the Backup System subsequently creates a dump at the dump
30 level, it uses the specified value to derive the dump's expiration date,
31 which it records on the label of the tape (or backup data file). The
32 Backup System refuses to overwrite a tape until after the latest
33 expiration date of any dump that the tape contains, unless the B<backup
34 labeltape> command is used to relabel the tape. If a dump level does not
35 have an expiration date, the Backup System treats dumps created at the
36 level as expired as soon as it creates them.
38 (Note that the Backup System does not automatically remove a dump's record
39 from the Backup Database when the dump reaches its expiration date, but
40 only if the tape that contains the dump is recycled or relabeled. To
41 remove expired and other obsolete dump records, use the B<backup
44 Define either an absolute or relative expiration date:
50 An absolute expiration date defines the month/day/year (and, optionally,
51 hour and minutes) at which a dump expires. If the expiration date predates
52 the dump creation time, the Backup System immediately treats the dump as
57 A relative date defines the number of years, months, or days (or a
58 combination of the three) after the dump's creation that it expires. When
59 the Backup System creates a dump at the dump level, it calculates an
60 actual expiration date by adding the relative date to the start time of
69 =item B<-dump> <I<dump level name>>+
71 Names each dump level to add to the dump hierarchy. Precede full dump
72 level names with a slash (for example, C</full>). Indicate an incremental
73 dump level by preceding it with an ordered list of the dump levels
74 directly above it in the hierarchy (its parent dump levels); use the slash
75 as a separator. The parent dump levels must already exist. For example,
76 the dump levels C</full> and C</full/incremental1> must exist when the
77 incremental dump level C</full/incremental1/incremental2> is created.
79 Dump level names can have any number of levels, but cannot exceed 256
80 characters in length, including the slashes. The maximum length for any
81 single level (the text between slashes) is 28 characters, not including
84 All alphanumeric characters are allowed in dump level names. Do not use
85 the period (C<.>), however, because it is the separator between the volume
86 set name and dump level name in the dump name assigned automatically by
87 the B<backup dump> command. It is best not to include other metacharacters
88 either; if using them, enclose them in double quotes (C<" ">) when issuing
89 the B<backup adddump> command outside interactive mode.
91 =item B<-expires> <I<expiration date>>+
93 Defines the absolute or relative expiration date to associate with each
94 dump level named by the B<-dump> argument. Absolute expiration dates have
97 [at] {NEVER | <mm>/<dd>/<yyyy> [<hh>:<MM>] }
99 where the optional word at is followed either by the string C<NEVER>,
100 which indicates that dumps created at the dump level never expire, or by a
101 date value with a required portion (<mm> for month, <dd> for day, and
102 <yyyy> for year) and an optional portion (<hh> for hours and <MM> for
105 Omit the I<hh:MM> portion to use the default of midnight (00:00 hours), or
106 provide a value in 24-hour format (for example, C<20:30> is 8:30 p.m.).
107 Valid values for the year range from C<1970> to C<2037>; higher values are
108 not valid because the latest possible date in the standard UNIX
109 representation is in February 2038. The command interpreter automatically
110 reduces later dates to the maximum value.
112 Relative expiration dates have the following format:
114 [in] [<years>y] [<months>m] [<days>d]
116 where the optional word in is followed by at least one of a number of
117 years (maximum C<9999>) followed by the letter C<y>, a number of months
118 (maximum C<12>) followed by the letter C<m>, or a number of days (maximum
119 C<31>) followed by the letter C<d>. If providing more than one of the
120 three, list them in the indicated order. If the date that results from
121 adding the relative expiration value to a dump's creation time is later
122 than the latest possible date in the UNIX time representation, the Backup
123 System automatically reduces it to that date.
127 Constructs a server ticket using a key from the local
128 F</usr/afs/etc/KeyFile> file. The B<backup> command interpreter presents
129 it to the Backup Server, Volume Server and VL Server during mutual
130 authentication. Do not combine this flag with the B<-cell> argument. For
131 more details, see L<backup(8)>.
133 =item B<-cell> <I<cell name>>
135 Names the cell in which to run the command. Do not combine this argument
136 with the B<-localauth> flag. For more details, see L<backup(8)>.
140 Prints the online help for this command. All other valid options are
147 The following command defines a full dump called C</1999> with a relative
148 expiration date of one year:
150 % backup adddump -dump /1999 -expires in 1y
152 The following command defines an incremental dump called
153 C</sunday1/monday>1 with a relative expiration date of 13 days:
155 % backup adddump -dump /sunday1/monday1 -expires in 13d
157 The following command defines two dump incremental dump levels,
158 C</Monthly/Week1> and C</Monthly/Week2>. Their parent, the full dump level
159 C</Monthly>, must already exist. The expiration date for both levels is
160 12:00 a.m. on 1 January 2000.
162 % backup adddump -dump /Monthly/Week1 /Monthly/Week2 -expires at 01/01/2000
