6 vos backupsys -- create Backup volume version of all
8 indicated ReadWrite volumes.
11 vos backupsys [-prefix <common prefix on volume(s)>]
12 [-server <machine name>] [-partition <partition name>]
13 [-cell <cell name>] [-noauth] [-localauth] [-verbose]
16 ACCEPTABLE ABBREVIATIONS/ALIASES
18 vos backups [-pr <common prefix on volume(s)>] [-s
20 [-pa <partition name>] [-c <cell name>] [-n] [-l] [-v]
25 Clones each indicated ReadWrite volume to make a Backup
26 version of it. Names each Backup version by adding a
27 .backup extension to the name of its ReadWrite source. It
28 places each Backup at the same site as its source, and
29 changes the VLDB status flag for each Backup to valid.
31 If a Backup version already exists for a volume, the new
32 clone replaces it. The status flag remains valid.
34 By combining the -prefix, -server and -partition arguments
35 in different ways, it is possible to create Backup copies of
36 varying numbers of volumes. The possibilities are listed
37 here from most to least inclusive
39 To create a Backup version of:
41 - every ReadWrite volume in the system, omit all
42 three arguments. This could take a rather long
43 time to execute, depending on the number of
46 - every ReadWrite volume whose name begins with a
47 certain character string (for example, sys. or
48 user.), regardless of site, use -prefix.
50 - every ReadWrite volume on a file server machine,
51 specify the file server name with -server.
53 - every ReadWrite volume that resides on a partition
54 of the same name (for instance, on /vicepa on any
55 file server machine), specify the partition name
58 - every ReadWrite volume on a certain partition of a
59 file server machine, specify both -server and
64 - every ReadWrite volume with a certain prefix that
65 resides on a file server machine, combine -prefix
66 and -server. The -prefix argument may also be
67 combined with -partition, or both -server and
68 -partition, in this way.
70 - a single ReadWrite volume, give its complete name
71 as -prefix. This is actually better done with the
72 vos backup command, which employs a more
73 streamlined technique for finding a single volume.
77 -prefix specifies a character string of any length.
78 Every volume whose name begins with this
79 exact string will be cloned (subject to
80 modulations from -server and -partition).
81 Include field separators (such as periods)
82 if appropriate. This argument may be
83 combined with -server and/or -partition.
85 -server names the file server machine where the
86 ReadWrite source volume(s) reside.
87 Abbreviated forms of machine names may be
88 allowed depending on the naming service
89 available at the time the command is issued;
90 see page xii in the introductory About This
91 Manual chapter. This argument may be
92 combined with -prefix and/or -partition.
94 -partition names the particular partition where the
95 ReadWrite source volume(s) reside. In
96 addition to the full /vicepx form of a
97 partition name, three shorter forms are
98 acceptable; see page xii in the introductory
99 About This Manual chapter. This argument
100 may be combined with -prefix and/or -server.
102 -cell specifies the cell in which to run the
103 command. See section 8.3 in the Reference
104 Manual for more details. -noauth
105 tells the Volume and Volume Location Servers
106 to assign the identity anonymous to the
107 issuer. See section 8.3 in the Reference
108 Manual for more details. -localauth
109 constructs a server ticket using a key from
110 /usr/afs/etc/KeyFile. See section 8.3 in
111 the Reference Manual for more details.
113 tells the Volume and Volume Location Servers
114 to report on what they are doing as they
115 execute the command. See section 8.3 in the
116 Reference Manual for more details. -help
117 prints the online help for this command. Do
118 not provide any other arguments or flags
119 with this one. See section 8.3 in the
120 Reference Manual for more details.
126 The following creates a Backup version of every volume in
127 the cell's file system whose name begins with "user".
131 The following, appropriate in the Transarc Corporation cell,
132 creates a Backup version of every volume on the file server
133 machine fs3.transarc.com.
135 % vos backups -s fs3.transarc.com
137 The following, appropriate in the Transarc Corporation cell,
138 creates a Backup version of every volume on the /vicepc
139 partition of the file server machine fs5.transarc.com.
141 % vos backups -s fs5.transarc.com -p c
143 The following, appropriate in the Transarc Corporation cell,
144 creates a Backup version of every volume on the file server
145 machine db1.transarc.com whose name begins with "sys".
147 % vos backups sys db1.transarc.com
151 Issuer must be listed in /usr/afs/etc/UserList on -server.
